- 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

- 16:33:44 [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

- 17:07:21 [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
