16:14:46 <Ashok> Satya will contact Susie Stephens
16:15:05 <Soeren> no discussions about RIF today
16:15:25 <Soeren> Ashok reports about Semantic Web gathering last Tuesday
16:16:01 <Soeren> takes place regularly at MIT and organized by Kingsley
16:16:19 <Soeren> Ashok reports about positive feedback
16:17:38 <Soeren> Andrew from W3C supports RIF serialization of a mapping language
16:18:29 <Soeren> creative commons aims at starting a common naming workgroup
16:19:55 <Soeren> similar to ENS (and LSID)
16:21:32 <Soeren> use cases should be referenced from the recommendation
16:23:24 <Soeren> Orri: integration and interoperability justify the need for a mapping language
16:24:10 <Soeren> http://linkedgeodata.org/
16:25:07 <Ashok> Data from Open Streets
16:25:44 <Ashok> Distributed World Wide Community ... anyone can contribute
16:26:35 <Ashok> Data can be published as RDF.  They use Triplify
16:26:59 <Soeren> http://linkedgeodata.org/browser/
16:27:08 <Ashok> There is also a facet-based browser for this data
16:27:55 <Ashok> can search for bicycle-shops for example
16:28:16 <Ashok> Open Street Maps
16:28:46 <Ashok> Relational data structure but close to RDF
16:30:18 <Soeren> OSM schema consists of relations and RDF like structures
16:30:45 <Ashok> Each point and way as a unique ID
16:31:31 <Soeren> points and ways are tagged with property value combinations
16:31:50 <Ashok> That is FK into a tag table ... which has Mant-to-Many Rels from point to way ... 1 to M from Way to Tag
16:32:20 <Ashok> Soeren propoert-vale annotations on each point or way
16:32:29 <Zakim> -Satya
16:33:07 <Zakim> +??P15
16:33:44 <Ashok> People shd try it out  .... still work in progress ... setting up Wiki etc.
16:34:56 <Ashok> Data is open, people can add and modify it... can create own properties and, in fact, new applications
16:36:07 <Ashok> There is a website called MapMyRun which tells you where you can run anywhere in the world.
16:36:39 <iv_an_ru> (Alan Ruttenberg should look at linkedgeodata. By replacing Earth map with X-Ray snapshot of, say, brain, he may get an interesting tutorial application)
16:36:55 <Soeren> OSM applies the wiki approch to geo data
16:36:58 <Ashok> Can be more detailed.   Depends on the community.  Liepzig and london are very detailed.  Much more info than Google Maps
16:37:37 <Soeren> Ivan sent email on the ordenance survey use case
16:39:37 <Soeren> http://lists.w3.org/Archives/Public/public-xg-rdb2rdf/2008Nov/0027.html
16:41:13 <Soeren> Orri: mapping geo-graphical joining requires special SPARQL support
16:43:18 <Soeren> OpenLink will look into the ordinance survey use case once logistics are clarified
16:44:54 <Soeren> one week of work for OpenLink (after setup of the infrastructure) to create a showcase on using SPARQL for handling ordinance survey geo data
16:45:18 <Soeren> Orri estimates most workload can be pushed down into the DB
16:46:49 <Ashok> ACTION:  Orri to write up Ordnance Survey Usecase by early January.  Discuss on Jan 9 telcon.
16:47:47 <Ashok> Topic:  XG Recommendation
16:47:48 <Soeren> talk about XG recommendation
16:47:52 <Ashok> http://esw.w3.org/topic/Rdb2RdfXG?action=AttachFile&do=view&target=ProposedRecommendation 
16:51:54 <Soeren> ACTION: Ashok will send recommendation draft to mailing list
16:55:57 <Ashok> Ahmed:  How about a JDBC like interface that takes a SPARQL query and refurns RDF
16:56:46 <iv_an_ru> Why "JDBC like"? Use JDBC...
16:57:59 <Soeren> Orri says SPARQL and SQL can be mixed and used together
16:58:45 <Soeren> SQL should be writeable inside SPARQL
16:59:00 <iv_an_ru> If needed, I'll implement that quickly
16:59:31 <Soeren> DAG working group exists
16:59:42 <iv_an_ru> Actually, some SQL fragments appear in our mapping rules already, so the required infrastructure is in place.
16:59:51 <Ashok> s/DAG/DAWG/
17:00:48 <Soeren> fairly limited scope right now in DAWG
17:01:36 <Ashok> Orri:  Put a SQL view in SPARQL instead of graph-pattern
17:02:04 <Ashok> SPARQL must have views and these may be SQL-views
17:03:46 <Soeren> satya asks whether a SPARQL view can be considered as a sub graph
17:04:02 <Ashok> Satya:  Would a SPARQL-view be a ub-graph?
17:04:12 <Ashok> Orri:  It would be a derived table
17:05:28 <Soeren> in-completeness of SPARQL complicates the problem
17:06:42 <Soeren> ACTION: Ashok we remind on the public list on documents for review by the group
17:07:09 <Soeren> next meeting 9th of Jan 2009

17:07:20 <Zakim> INC_RDB2RDF()11:00AM has ended
17:07:21 <Zakim> Attendees were Ashok_Malhotra, Andrew_Eisenberg, Satya, Soeren, Wolfgang, [IPcaller], iv_an_ru
17:07:57 <Ashok> Soeren:  Result of SPARQL query is not always a graph ... SPARQL does not have relational completeness.  Not easy to acheive.
17:08:49 <Ashok> rrsagent, make logs public
17:08:59 <Ashok> rrsagent, create minutes
17:08:59 <RRSAgent> I have made the request to generate http://www.w3.org/2008/12/12-RDB2RDF-minutes.html Ashok
