satya will send state-of-the-art document in first week of Jan
satya requests timeslot for presentation about mapping clinical data to RDF
<Ashok> Satya will contact Susie Stephens
no discussions about RIF today
Ashok reports about Semantic Web gathering last Tuesday
takes place regularly at MIT and organized by Kingsley
Ashok reports about positive feedback
Andrew from W3C supports RIF serialization of a mapping language
creative commons aims at starting a common naming workgroup
similar to ENS (and LSID)
use cases should be referenced from the recommendation
Orri: integration and interoperability justify the need for a mapping language
<Ashok> Data from Open Streets
<Ashok> Distributed World Wide Community ... anyone can contribute
<Ashok> Data can be published as RDF. They use Triplify
http://linkedgeodata.org/browser/
<Ashok> There is also a facet-based browser for this data
<Ashok> can search for bicycle-shops for example
<Ashok> Open Street Maps
<Ashok> Relational data structure but close to RDF
OSM schema consists of relations and RDF like structures
<Ashok> Each point and way as a unique ID
points and ways are tagged with property value combinations
<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
<Ashok> Soeren propoert-vale annotations on each point or way
<Ashok> People shd try it out .... still work in progress ... setting up Wiki etc.
<Ashok> Data is open, people can add and modify it... can create own properties and, in fact, new applications
<Ashok> There is a website called MapMyRun which tells you where you can run anywhere in the world.
<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)
OSM applies the wiki approch to geo data
<Ashok> Can be more detailed. Depends on the community. Liepzig and london are very detailed. Much more info than Google Maps
Ivan sent email on the ordenance survey use case
http://lists.w3.org/Archives/Public/public-xg-rdb2rdf/2008Nov/0027.html
Orri: mapping geo-graphical joining requires special SPARQL support
OpenLink will look into the ordinance survey use case once logistics are clarified
one week of work for OpenLink (after setup of the infrastructure) to create a showcase on using SPARQL for handling ordinance survey geo data
Orri estimates most workload can be pushed down into the DB
<Ashok> ACTION: Orri to write up Ordnance Survey Usecase by early January. Discuss on Jan 9 telcon. [recorded in http://www.w3.org/2008/12/12-RDB2RDF-minutes.html#action01]
talk about XG recommendation
<Ashok> http://esw.w3.org/topic/Rdb2RdfXG?action=AttachFile&do=view&target=ProposedRecommendation
<scribe> ACTION: Ashok will send recommendation draft to mailing list [recorded in http://www.w3.org/2008/12/12-RDB2RDF-minutes.html#action02]
<Ashok> Ahmed: How about a JDBC like interface that takes a SPARQL query and refurns RDF
<iv_an_ru> Why "JDBC like"? Use JDBC...
Orri says SPARQL and SQL can be mixed and used together
SQL should be writeable inside SPARQL
<iv_an_ru> If needed, I'll implement that quickly
DAWG working group exists
<iv_an_ru> Actually, some SQL fragments appear in our mapping rules already, so the required infrastructure is in place.
fairly limited scope right now in DAWG
<Ashok> Orri: Put a SQL view in SPARQL instead of graph-pattern
<Ashok> SPARQL must have views and these may be SQL-views
satya asks whether a SPARQL view can be considered as a sub graph
<Ashok> Satya: Would a SPARQL-view be a ub-graph?
<Ashok> Orri: It would be a derived table
in-completeness of SPARQL complicates the problem
<scribe> ACTION: Ashok we remind on the public list on documents for review by the group [recorded in http://www.w3.org/2008/12/12-RDB2RDF-minutes.html#action03]
next meeting 9th of Jan 2009
<Ashok> Soeren: Result of SPARQL query is not always a graph ... SPARQL does not have relational completeness. Not easy to acheive.
