07:47:34 <mhausenblas> 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

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> Michael: +1
08:32:30 <juan> Juan: +1
08:32:47 <mhausenblas> RESOLUTION: The language will have a human-readable syntax as well as an XML and RDF representation for purposes of discovery and automatic generation.

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> Soeren has joined #rdb2rdf
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.'
09:10:02 <mhausenblas> Michael: +1
09:10:02 <Cathy> +1

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.

09:43:03 <mhausenblas> Ashok: 'the WG must track the evolution of SPARQL and liaise with the DAWG'
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'
