== Project Description ==

The [http://en.wikipedia.org/wiki/Open_Data Open Data Movement] aims at making data freely available to everyone.
There are already various interesting open data sets available on the Web. Examples include [http://www.wikipedia.org/ Wikipedia], [http://www.wikipedia.org/ Wikibooks], [http://www.geonames.org/ Geonames], [http://musicbrainz.org/ MusicBrainz], [http://wordnet.princeton.edu/online/ WordNet],
the [http://www.informatik.uni-trier.de/~ley/db/ DBLP bibliography] and many more which are published under [http://creativecommons.org/ Creative Commons] or [http://www.talis.com/tdn/tcl Talis] licenses.

The goal of the W3C SWEO Linking Open Data community project is to extend the Web with a data commons by publishing various open data sets as RDF on the Web and by setting RDF links between data items from different data sources.

RDF links enable you to navigate from a data item within one data source to related data items within other sources using a Semantic Web browser. RDF links can also be followed by the crawlers of Semantic Web search engines, which may provide sophisticated search and query capabilities over crawled data. As query results are structured data and not just links to HTML pages, they can be used within other applications.

<span id="dbpedia-lod-cloud"></span> The figures below show the data sets that have been published and interlinked by the project so far. Collectively, the 570 data sets are connected by 2909 link sets.

=== Mailing List ===

As there are lots of interesting mail conversations around the project, we decided that we need a mailing list.

The list is hosted by W3C and you can subscribe it at [http://lists.w3.org/Archives/Public/public-lod/].

The project's mailing list was hosted by the [http://simile.mit.edu/ MIT SIMILE project] until Spring 2008; MIT also maintains an [http://simile.mit.edu/mail/SummarizeList?listId=14 archive] of the list until that point.

== FAQ ==

'''1. Please provide a brief description of your proposed project.'''

The [http://en.wikipedia.org/wiki/Open_Data Open Data Movement] aims at making data freely available to everyone.
There are already various interesting open data sources available on the Web. Examples include [http://www.wikipedia.org/ Wikipedia], [http://www.wikipedia.org/ Wikibooks], [http://www.geonames.org/ Geonames], [http://musicbrainz.org/ MusicBrainz], [http://wordnet.princeton.edu/online/ WordNet],
the [http://www.informatik.uni-trier.de/~ley/db/ DBLP bibliography] and many more which are published under [http://creativecommons.org/ Creative Commons] or [http://www.talis.com/tdn/tcl Talis] licenses.

The goal of the Linking Open Data project is to build a data commons by making various open data sources available on the Web as RDF and by setting RDF links between data items from different data sources.

RDF links enable you to navigate from a data item within one data source to related data items within other sources using a Semantic Web browser. RDF links can also be followed by the crawlers of Semantic Web search engines, which may provide sophisticated search and query capabilities over crawled data. As query results are structured data and not just links to HTML pages, they can be used within other applications.

There are already some data publishing efforts. Examples include the [http://dbpedia.org/docs/ DBpedia.org] project, the [http://www.geonames.org/ontology/ Geonames Ontology], the [http://www4.wiwiss.fu-berlin.de/dblp/ D2R Server publishing the DBLP bibliography] and the [http://moustaki.org/dbtune/ dbtune] music server.
There are also initial efforts to interlink these data sources. For instance, the DBpedia RDF descriptions of cities includes owl:sameAs links to the Geonames data about the city [http://dbpedia.org/docs/#link (1)]. Another example is the [http://sites.wiwiss.fu-berlin.de/suhl/bizer/bookmashup/ RDF Book Mashup] which links book authors to paper authors within the DBLP bibliography [http://lists.w3.org/Archives/Public/semantic-web/2006Dec/0022 (2)].

'''2. Why did you select this particular project?'''

For demonstrating the value of the Semantic Web it is essential to have more real-world data online. RDF is also the obvious technology to inter-link data from various sources.

'''3. Why do you think this project will have a wide impact?'''

A huge inter-linked data set would be beneficial for various Semantic Web development areas, including Semantic Web browsers and other user interfaces, Semantic Web crawlers, RDF repositories and reasoning engines.

Having a variety of useful data online would encourage people to link to it and could help bootstrapping the Semantic Web as a whole.

'''4. Can your project be easily integrated with other wide-spread systems? If so, which and how?'''

The data can instantly be browsed with Semantic Web browsers like [http://dig.csail.mit.edu/2005/ajar/ajaw/About.html Tabulator] or [http://sites.wiwiss.fu-berlin.de/suhl/bizer/ng4j/disco/ Disco] or [http://demo.openlinksw.com/rdfbrowser/ OpenLink RDF Browser] or [http://ode.openlinksw.com/ OpenLink Data Explorer].
Existing Semantic Web crawlers like [http://www.swse.org/ SWSE], [http://swoogle.umbc.edu/ Swoogle] can provide an integrated view on the data and sophisticated search interfaces.

'''5. Why is it that this project should be done right now, i.e. why should people prioritize this ahead of other projects?'''

It is getting boring to play around with toy examples as most Semantic Web projects do.

'''6. What can you contribute to the project?'''

We will keep on working on DBpedia and start serving RDF for all 1.6 million concepts in Wikipedia in a couple of weeks. As Wikipedia contains information about various domains, we think DBpedia URIs could function as a valuable linking-hub for interconnecting various data sources. We could link to related data from DBpedia as we already did with the links to Geonames.

'''7. What contribution would you need from others?'''

* Propose additional open data sources that could be mapped to RDF.
* Convert a data source to RDF and serve it as linked data or SPARQL endpoint on the Web.
* Invent heuristics to auto-generate links between data items from different sources.

'''8. What standardization should the Semantic Web community at large undertake to support the project?'''

There is already standardization going on within the SWBP working group:  [http://www.w3.org/TR/swbp-vocab-pub/ Best Practice Recipes for Publishing RDF Vocabularies].
It would also be useful to propagate Tim's [http://www.w3.org/DesignIssues/LinkedData.html linked data] ideas.

'''9. How does your project encourage others not currently involved with Semantic Web technologies to get involved (by providing data or make a coding commitment)?'''

Having useful data online might initialize network effects. The project could raise awareness within the Open Data community about the benefits that RDF as a shared data model offers them. Having richly inter-linked data online might inspire people to create interesting mashups and other RDF-aware applications.

'''10. What would be the main benefit of using Semantic Web technologies to achieve the goals of the project, compared to other technologies?'''

RDF provides a flexible data model for integrating information from different sources. Especially its [http://www.w3.org/DesignIssues/LinkedData.html linking capabilities] are not provided by any other data model.

== Commitments ==

If you like this project, please write your name below and indicate what contribution you can make to the project. Possible forms of commitment are:

* I think this project is a good idea and it's realization would be useful.
* I would like to propose further data sources for being published as RDF
* I would like to convert a data source to RDF
* I could serve some data from my server (if somebody would give it to me)
* I would like to work on heuristics to auto-generate links between data items from different sources
* I could talk with other people that might want to contribute to the project

[http://sites.wiwiss.fu-berlin.de/suhl/ueber_uns/team/chris_bizer.htm Chris Bizer] and [http://richard.cyganiak.de/ Richard Cyganiak] proposed the project to the W3C SWEO. We maintain several Linked Data sources, including DBpedia, DBLP Berlin, CIA Factbook, Book Mashup and Eurostat, and do outreach and coordination work for the project.

[http://www.informatik.uni-leipzig.de/~auer Sören Auer] - I try to contribute with regard to converting, serving data-sources and talking to people ;-)

[http://en.wikipedia.org/wiki/User:Universimmedia Bernard Vatant] - Already involved in Geonames ontology, and linking Geonames data and concepts to other sources such as INSEE data. Projects to do more, linking to GEMET concepts, Wikipedia categories etc.

[http://razor.occams.info Josh Tauberer] - 700 million triples of U.S. Census data coming very soon now.... (Just having some free disk space issues loading it into MySQL.)  Tying this to [[GeoNames]] will be an interesting/useful project for someone looking for a project.

[http://tomheath.com/id/me Tom Heath] - Great idea. I can contribute the involvement of [http://revyu.com/ Revyu.com], (AFAIK) the only RDF-based reviewing and rating site in the wild. The sites exposes data using FOAF, the [http://purl.org/stuff/rev# Review Vocab] and Richard Newman's [http://www.holygoat.co.uk/owl/redwood/0.1/tags/ Tag Ontology], and everything gets dereferenceable URIs. The data set is modest, but growing. I'm really interested in developing heuristics to auto-generate sameAs links between URIs from Revyu and elsewhere, and ways to infer locations of things from reviews and tags and hook this into Geonames.

[[KingsleyIdehen|Kingsley Idehen]], [[OrriErling|Orri Erling]], and [[FrederickGiasson|Frederick Giasson]] - Additional and complementary RDF Data Sources in line with Linked Data principles via projects such as [[PingTheSemanticWeb]], [[SearchTheSemanticWeb]], and [[OpenLinkDataSpaces|OpenLink Data Spaces]]. In addition we will be making [[VirtuosoUniversalServer|Virtuoso]] available as an RDF Data Store for scalability experimentation, exploration activities, etc.

[http://www.geonames.org Marc Wick] - Implementation of Geonames RDF web services

[http://www.felixvandemaele.net Felix Van de Maele] - A very interesting project. I developed an ontology-focused crawler and am currently working on the community-driven ontology matcher and mediator which might be handy to interlink RDF data sources.

[http://simile.mit.edu Stefano Mazzocchi] - As part of the MIT Simile Project, I've been RDFizing large data sets for years (unfortunately, most of these are not data I can make publicly available). We provide a way to export RDF data from all of our RDF browsing tools, but we haven't focused on providing URI dereferencing for such data and I agree that it might be important to start doing so. The juiciest dataset we have to offer is a 50Mt dump of the MIT Libraries catalog covering about a million books. I'm also currently working on an owl:sameAs-based RDF smoosher (which is already functional from the command line) and I'm planning on working on equivalence mining next. Also worth noting how the SIMILE Project has a large collection of RDFizing programs that can be used to generate large quantities of RDF from existing data.

[[DannyAyers]] - intend to look at [[ConverterFromRdf]] possibilities, linking the output semweb systems to "legacy" data consumers, also wondering about low-cost linkage/heuristics for describing data sets

[http://inkdroid.org Ed Summers] - I'm a software developer at the Library of Congress interested in making bibliographic and authority data sets available to the semantic web.

[http://moustaki.org/ Yves Raimond] - I am a PhD student in the Centre for Digital Music, Queen Mary, University of London, and I am interested in linking music-related open data (Musicbrainz,
[http://www.magnatune.com/ Magnatune], [http://www.jamendo.com/ Jamendo], [http://www.dogmazic.net/ Dogmazic],
[http://www.mutopiaproject.org/ Mutopia], among others...). I am also part of two projects, in which I am trying to promote such an approach: [http://www.easaier.org/ EASAIER] (Enabling Access to Sound
Archives through Enrichment and Retrieval) and [http://omras2.doc.gold.ac.uk/ OMRAS2] (Online Music Recognition and
Searching).

[http://www.semanticweb.gr Vangelis Vassiliadis] - I could work on heuristics to auto-generate links between data items from different sources and on adding domain knowledge to different
data sets by means of OWL.

[[DmitryUlanov|Dmitry Ulanov]] - I'm a developer of [http://esw.w3.org/topic/TaskForces/CommunityProjects/LinkingOpenData/THALIATestbed THALIA testbed]. It can be used for benchmarking relational database to RDF mapping tools.

[http://www.georgikobilarov.com Georgi Kobilarov] - I maintain the [http://dbpedia.org DBpedia] extraction framework. I'm interested in developing tools to help data publishers interlink their databases and in building UIs for end-users .

[[HuajunChen|Huajun Chen]] - developer of [http://ccnt.zju.edu.cn/projects/dartgrid/ DartGrid] which is a relational data integration toolkit using semantic web technologies. Two major components of [[DartGrid]] are a visulized semantic mapping tool and a view-based(or more generally rule-based) SPARQL-SQL query rewriting component.  [http://www.informatik.uni-trier.de/~ley/db/conf/semweb/iswc2006.html#ChenWWMTZYW06 ISWC2006 Paper] introduces the details.

[[ChrisWilper|Chris Wilper]] - I'm a developer of [http://www.fedora.info/ Fedora] and also work with the [http://nsdl.org/ National Science Digital Library] group at Cornell.  I'm interested in the collaborative development of OLTP benchmarks for triplestores.

[http://www.g1o.net Giovanni Tummarello] - I created [http://www.activerdf.org/sindice/ Sindice], together with [http://eyaloren.org/ Eyal Oren]. Sindice is a linked data search engine which returns ranked lists of "SeeAlso" URLs which contain information about a given URI. In a sense it overcomes the problem of the need of the mandatory "SeeAlso" statements by looking anywhere on the web (via people providing direct Ping either to ourself or to PTSW and via our array of [http://swse.deri.ie swse] bots). "SeeAlso" statemens remain useful however for ranking purposes. Service has a simple http API, see for example all the links Sindice knows which talk about Tim Berners-Lee [http://www.sindice.com/query/lookup?uri=http%3A%2F%2Fwww.w3.org%2FPeople%2FBerners-Lee%2Fcard%23i here].

[[ShermanMonroe|Sherman D. Monroe]] - I'm the author of [http://cypher.monrai.com Cypher], which is a transcoder with generates the RDF and SeRQL (working on SPARQL port) representation of natural language phrases and sentences. The [http://projects.semwebcentral.org/projects/cypher/ project page can be found here]. The Cypher project aims to collect and unify the various sources of data used for NLP tasks, such as [[WordNet]], [[FrameNet]], [[PropBank]], as well as annotated corpora, and also to provide standard ontologies for things like part-of-speech tagging. We wish to provide a single resource which NLP applications can use to leverage this data. I'm also working on a Semantic Web web service called [http://www.overdogg.com overdogg] (currently in alpha) which is a new type of marketplace based on reverse auction for services, and another soon to be announced service which builds FOAF databases of users.

[http://technorati.com/blogs/semanticdeveloper Adam Sobieski] - Interested in event ontology and also wikitology.  I'm making a website that allows users to select or create predicates and drag and drop nouns (noun phrases) from sentences into predicate slots.  The interface will capture pronoun resolution and semantics from visitors reading.  The sentences will be viewed in order from articles to obtain context information.  The downloadable resource will be both a corpus (hopefully as useful as Penn treebank and Redwoods) and a collaborative ontology relating nouns from real-world encyclopedic articles.

[http://www.mpi-inf.mpg.de/~suchanek Fabian M. Suchanek] and [http://www.mpi-inf.mpg.de/~kasneci Gjergji Kasneci] - We provide [http://www.mpi-inf.mpg.de/yago YAGO], a large ontology. YAGO is available for querying and for download in different formats (RDFS, XML, database, text).

[[TroySelf|Troy Self]] - I maintain [http://www.semwebcentral.org SemWebCentral], which is a development site for Open Source Semantic Web tools. I also maintain the RDF browser, [http://objectviewer.semwebcentral.org ObjectViewer], the ontology summarizer, [http://ocelot.semwebcentral.org Ocelot], and was one of the primary developers of the Semantic Web Development Environment, [http://owl-eclipse.projects.semwebcentral.org SWeDE].

[http://www.cs.univie.ac.at/bernhard.haslhofer Bernhard Haslhofer] - I am working on Semantic Web topics in the Digital Library and Archives domain. An easy way to link [http://www.openarchives.org/Register/BrowseSites hundreds of data sources] would be to build a wrapper for the [http://www.openarchives.org/OAI/openarchivesprotocol.html Open Archives Protocol for Metadata Harvesting (OAI-PMH)]. I intend to get some work done in this direction.

[[DavidPeterson|David Peterson]] - I am working on getting large Australian science data sets converted to RDF and accessible via SPARQL. We work with over 13 large and diverse science organisations so I believe this will be a valuable contribution.

[http://www.l3s.de/~diederich Joerg Diederich] - I am working on Semantic Web topics and Digital Libraries and I am the maintainer of [http://dblp.l3s.de FacetedDBLP]. I am planning to contribute my local DBLP data (updated weekly) by means of the D2R technology from FUBerlin very soon.

[[DannyGagne|Danny Gagne]] -- I think this is a great idea. I'm going to work on building some tools, trying to create a small dataset, who knows what else :)

[[MichaelHausenblas|MichaelHausenblas]] -- I joined the LOD community project in June 2007 after Chris Bizer has told me about this great idea. In the meantime quite some things emerged and I think I have left some traces ;) In the beginning I was interested in building a linked dataset, which actually yielded [http://riese.joanneum.at/ riese], the RDFised and interlinked version of the Eurostat's statistical data. As a by-product we developed a pradigm allowing for manual interlinking, called [http://sw-app.org/pub/eswc08-irs-poster.pd UCI] (User-Contributed Interlinking). Then my focus shifted and I wanted to build applications on top of linked data [http://lists.w3.org/Archives/Public/public-lod/2008May/0024.html which triggered] the creation of [http://semanticweb.org/wiki/VoiD voiD], the 'Vocabulary of Interlinked Datasets'. Now, as I'm a multimedia guy at heart, I also started to [http://www.interlinkingmultimedia.info/ apply linked data principles to multimedia content]. Finally, I gave a [http://events.linkeddata.org/iswc2008tutorial/ LOD tutorial] at ISWC08 with Tom, Chris, Richard and Olaf (see also my [http://www.slideshare.net/mediasemanticweb/quick-linked-data-introduction/ quick intro into linked data]). I've participated in (and co-organised) several LOD Gatherings so far and plan to do so in the future.

[[JonathanGray|Jonathan Gray]] -- I'm from the [http://www.okfn.org Open Knowledge Foundation] and I'm interested in [http://www.okfn.org/wiki/OpenDataLicensing open data licensing] and [http://www.ckan.net/ locating and listing open data sets].

[[BernhardSchandl|Bernhard Schandl]] -- I am working on integration of semantic data into user desktops and file systems and am interested in the possibilities of publishing such data on the web.

[[DavidHuynh|David Huynh]] -- I'm interested in building UIs for browsing and viewing the collected data. I don't think that a SPARQL interface appeals to the general public, and a pure search text box a la Google takes sufficient advantage of the graph nature of the data.

[[DanielLewis|Daniel Lewis]] -- I am a Technology Evangelist for [http://www.openlinksw.com/ OpenLink Software], my interests are in making the Social Web more Semantic, making the Semantic Web more User Friendly and making the web more intelligent. The only way to advance web applications is to expose and link data between domains - Semantic Web technology can do that. My blog is available [http://vanirsystems.com/danielsblog/ here] and I tend to talk about various subjects (not just about the Semantic Web).

[[AndreasLangegger|Andreas Langegger]] -- I'm currently developing a middleware for virtual data integration based on SW technologies. It will be used inside the Austrian Grid for sharing structured scientific data but because of the relevance for the SW community, it will be released as SemWIQ (Semantic Web Integrator and Query Engine) in mid-2008.  Among other goals, I try to keep setup / configuration as simple as possible. Stay tuned (currently optimization is on the top of the agenda)...

[[SergeyChernyshev|Sergey Chernyshev]] -- I'm running [http://www.techpresentations.org/ TechPresentations.org] project based on [http://www.semantic-mediawiki.org Semantic MediaWiki] (SMW) technologies and participating in a development community around SMW. Among my goals is to connect [[TechPresentations]] data to LOD dataset and to make use of SMW-related technologies to help crowd-sourced data get interconnected with other LOD data sets.

[[RobCakebread|Rob Cakebread]] -- I run [http://doapspace.org/ Doapspace.org] and am mainly interested in DOAP and linking it with FOAF, BEATLe, SIOC. I'm a Gentoo Linux developer and I'm working on tools for users and package maintainers to benefit from the metadata provided by DOAP and related ontologies.

[http://www.scharffe.fr Francois Scharffe] -- I'm a researcher at [http://www.sti2.at STI Innsbruck] in the area ontology alignment. I'm involved in the [http://www.easaier.org EASAIER] project where we publish music related data sets using the music ontology. I've worked on [http://www.scharffe.fr/pub/sparql++-for-mapping-between-rdf-vocabularies-ODBASE-2007.pdf SPARQL++], a SPARQL extension allowing to transfer RDF data from one ontology to another. I'm interested in data fusion techniques. I'm also interested creating a classical music reference knowledge base that could be used as an anchor to publish classical music data sets.

[http://esw.w3.org/topic/OktieH Oktie Hassanzadeh] -- I'm a graduate research assistant at the [http://www.cs.toronto.edu/ Department of Computer Science], [http://www.utoronto.ca/ University of Toronto] and a member of the [http://www.cs.toronto.edu/DB/ Database Group]. 
Together with [http://esw.w3.org/topic/MarianoConsens Mariano Consens], we developed the [http://www.linkedmdb.org Linked Movie DataBase] (LinkedMDB), that aims at publishing the first open linked data dedicated to movies. [http://www.linkedmdb.org LinkedMDB] showcases the capabilities of "ODDLinker", a tool under development, that employs state-of-the-art similarity join techniques for finding links between different data sources.

[[DanielSchwabe|Daniel Schwabe]] -- I'm a professor at [http://www.inf.puc-rio.br/ Department of Informatics, Catholic University of Rio de Janeiro], where I head the [http://tecweb.inf.puc-rio.br TecWeb Laboratory]. I work on design methods for (semantic) web applications seen as part of men-machine teams. We have developed Semantic Wiki authoring enviroments, and I am also trying to link the [http://portinari.org.br Portinari Project] data into the LoD cloud. We are also working on direct manipulation interfaces that allow users to explore RDF data sets, including querying, without requiring any knowledge of query languages.

[http://www.google.si/search?q=andraz+tori Andraz Tori] -- I'm CTO at [[Zemanta|Zemanta]]. I work on architecting Zemanta's engine to disambiguate to Linking Open Data entities. Would like to see which parts of LOD are candidates for inclusion into Zemanta and get the feedback of what the API needs to return to be most useful for enabling LOD mashups.

[[TedThibodeauJr|Ted Thibodeau Jr]] - I've been with [[OpenLinkSoftware|OpenLink Software]] since December 2000, working with Data Access and all that entails, including the Linking Open Data project, many aspects of the [[VirtuosoUniversalServer|Virtuoso Universal Server]], exposing more-and-less structured data (from RDBMS content to plaintext) as RDF, dreaming up new wish lists for Linked Data features and applications, connecting people and projects, and more.  My dream includes realization of the [http://dbpedia.org/page/Knowledge_Navigator Knowledge Navigator] [http://www.youtube.com/watch?v=3WdS4TscWH8 concept], complete with unrolled and/or unfolded screen, voice commands, intelligent agents, etc.  Before joining [[OpenLink]], I spent time serving various roles in various industries, all of which would have benefited from the LOD project, and those experiences guide my efforts today.

[http://harth.org/andreas/ Andreas Harth] -- I'm a researcher at DERI Galway, working on integrating web data without making assumptions on the schema used.  I currently crawl parts of the LOD (at least weekly) and provide search, browsing and navigation functionality over that LOD data in [http://visinav.deri.org/ VisiNav].  The site is useful for the LOD crowd as it allows people to inspect LOD data (including provenance tracking) in case there are hickups in the data published in the LOD cloud.

[http://hydrasi.com Hydrasi] -- I'm [[JohnMetta]], a scientist, 20+ year Open Source Software developer, and founder at Hydrasi. Hydrasi is a company focused on the water and climate sciences and we are planning on developing a non-profit foundation, the Climate Cloud Initiative, as an open data network of water and climate data. I'm happy to see such a diverse and active crowd in open data-- from so many fields.

[[TobyInkster]] - I'm Toby Inkster. Not sure why I've added myself to this list so late. Without exaggeration, I think Linked Data could play a part in solving some of the biggest problems of the 21st century. We can't really in advance which information will be turn out to be needed to save the world - the early scientists who caught lightning with kites could never have known that electricity and the things electronics have made possible would be so important in the modern age - so it's key to link together as much data as possible.

[http://mayor2.dia.fi.upm.es/index.php/en/phd/40-marianorico Mariano Rico] -- I developed [http://ishtar.ii.uam.es/fortunata/Wiki.jsp?page=VPOET VPOET], a web application oriented to create presentation templates for handling semantic data easily. As an example, click [http://ishtar.ii.uam.es/fortunata/servlet/VPoetRequestServlet?up_action=renderOutput&up_designID=FOAFOutputConditionalGraphics&up_provider=mra68&up_source=http://www.w3.org/People/Berners-Lee/card here] to browse TBL's FOAF profile under a given template.
These templates can be used also by web developers through HTTP messages, and end-users can use these templates by using the Google Gadget [http://www.google.es/ig/directory?&q=vpoet GG-VPOET]. You are welcome to create your own templates, reuse other's templates, or create your own templates repository ([http://code.google.com/p/fortunata/ code available]). I am enthusiastic with LOD and I think that semantic templates can contribute to reduce the adoption barrier of semantic data for common web developers and end-users.
