- Topic: Creating Identifiers
- 07:48:23 [mhausenblas]
- Ashok: Add requirement 'The language must allow for a mechanism to create identifiers for DB entities'
- 07:49:11 [mhausenblas]
- Themis: liasion with the OKKAM project that do ENS
- 07:49:37 [mhausenblas]
- Orri: should promote the reuse of identifiers
- 07:51:46 [mhausenblas]
- Themis: use unquie IDs, that is one URI for an entity rather than minting own URIs and connecting it via owl:sameAs
- 07:52:23 [mhausenblas]
- Orri: though owl:sameAs is not a good thing it is necessary
- 07:53:44 [mhausenblas]
- Michael: I have an action on this
- 07:54:36 [whalb]
- whalb has joined #RDB2RDF
- 07:54:43 [mhausenblas]
- Ashok: reuse for 'long-lived' entities such as persons, corporations
- 07:55:35 [mhausenblas]
- Ashok: propose to phrase the requirement as follows
- 07:56:57 [mhausenblas]
- ... 'The language must allow for a mechanism to create identifiers for DB entities. Where possible, the language will encourage the reuse of public identifiers for long-lived entities such as persons, corporations.'
- 07:56:59 [juan]
- juan has joined #RDB2RDF
- 07:59:33 [mhausenblas]
- RESOLUTION: 'The language must allow for a mechanism to create identifiers for DB entities. Where possible, the language will encourage the reuse of public identifiers for long-lived entities such as persons, corporations.'
- 07:59:57 [mhausenblas]
- Ashok: we will coopertate with OKKAM on that
- 08:01:21 [mhausenblas]
- Topic: Other Language Requirements
- 08:02:09 [mhausenblas]
- Ashok: propose to state that we will 'standardize a language for mapping RDB languages to RDF/OWL'
- 08:02:31 [mhausenblas]
- Soeren: learning curve should be low
- 08:03:02 [mhausenblas]
- Juan: Should have different levels/profiles
- 08:03:07 [mhausenblas]
- Michael: +1
- 08:04:05 [mhausenblas]
- Ashok: 'The language will have a human-readable syntax as well as an XML or RDF syntax'
- 08:05:47 [mhausenblas]
- Orri: add to this that 'the output will be defined in terms of an RDFS/OWL schema'
- 08:06:02 [juan]
- Juan: +1
- 08:07:42 [mhausenblas]
- Michael: important to offer different levels of expressivity for different use cases
- 08:13:18 [mhausenblas]
- Ashok: so we add 'It should be possible to subset the language for simple applications such as Web 2.0. The language will be validated by creating a library of mappings for widely used apps such as Drupal, Wordpress, phpBB.'
- 08:14:09 [Ashok]
- s/defined in terms/described by/
- 08:14:13 [mhausenblas]
- Michael: the lib can then be used for our test cases as well (volunteer to take over that part ;)

- 08:16:35 [mhausenblas]
- Jenny: So we are not being explicit about XML or RDF?
- 08:16:50 [mhausenblas]
- Michael: could use GRDDL to connect these both

- I have made the request to generate http://www.w3.org/2008/10/31-RDB2RDF-minutes.html mhausenblas
- 08:22:12 [mhausenblas]
- Orri: using XML as a base and provide a possibly non-complete mapping to RDF
- 08:31:16 [mhausenblas]
- Ashok: 'The language will have a human-readable syntax as well as an XML and RDF representation for purposes of discovery and automatic generation'
- 08:32:22 [mhausenblas]

- 08:38:14 [mhausenblas]
- Ivan: we should add 'language should be complete regarding the expressivity of relational algebra'
- 08:41:47 [mhausenblas]
- Ashok: ok, let's move on ... 'the language will allow customization wrt names, data manipulation.'
- 08:42:01 [mhausenblas]
- Orri: extensibility is important
- 08:52:25 [mhausenblas]
- Ashok: 'the language must be able to expose vendor specific SQL features such as full-text, spatial support, user-defined datatypes.'
- 08:55:55 [mhausenblas]
- Michael: +1
- 09:06:15 [Soeren]

- 09:09:12 [mhausenblas]
- Ashok: 'The mapping should allow the introduction of additional semantics, for example sub-classes, sub-properties, transitivity by utilising logics such as rules or DL languages.'

- 09:20:31 [mhausenblas]
- Ashok: Two more issues left
- 09:23:04 [mhausenblas]
- ... include non-relational data?
- 09:24:05 [mhausenblas]
- [[Discussion of possible use cases such as spreadsheets, etc. - the XG thinks that we will not address this]]
- 09:29:49 [mhausenblas]
- Ashok: last (motivated by Bijan's presentation)
- 09:31:08 [mhausenblas]
- ... 'language spec should include guidance to mapping to a sbu-set of OWL such as OQL/QL or OWL/RL'
- 09:38:50 [mhausenblas]
- Michael: If we want to include that we need to be aware of the fact that the test cases are actually for agreeing on the concrete impact of a certain language feature. The spec is human-readable, implementors have some freedom in implementing it.

- 09:43:08 [mhausenblas]
- Michael: +1
- 09:44:35 [mhausenblas]
- Michael: what about linked data?
- 09:45:44 [mhausenblas]
- Orri: propose to add 'the language should be designed to support the implementation of the linked data princinpes http://www.w3.org/DesignIssues/LinkedData.html'
