Eric: The Scala code is attached to msg sent to the WG list

Ahmed: Souri, any progress?

Souri: I looked at what Soeren put in and compared with what we put in as XML syntax
... ideas are very similar
... some complex cases, otherwise very similar.
... Need to find the best syntax

Ahmed: How are teams communicating?

<mhausenblas> Michael: encourage to use the RDB2RDF WG mailing list

Michael: Pl. use WG mailing list

Souri: We may also have some private communication among the group.

Ahmed: We also discussed last week a f2f meeting during SemTech conference ... perhaps Sunday and Friday

Souri: I could edit the Wiki or I could send out proposals on email

Ahmed: Perhaps using email is better

Discussion about editing the Wiki

scribe: there is an editing history

Michael: We have not updated Wiki with f2f meeting dates

<trackbot> Created ACTION-27 - Invite Olaf some time in the future (will be decided by group) [on Michael Hausenblas - due 2010-02-23].

Angela: I'm here
... what were you asking me? I was on mute.
... I implemented first usecase and was able to integreate the data
... I cannot publish real data but I could publish some fake data

Orri asks abt relationship between entities

Angela: This is easy as we map to our ontology
... I have a demo with 10 data sources and ... pieces of data
... the data is a dump of MySQL and some text files
... we create a triple-store with this data. They have OKKAM ids in them.
... may need multiple triple stores
... when we create SQL queries we can add where the data resides

Orri: May want to keep data relationally if schema does not change too often

Angela: I can add examples

Eric: I would be useful if it was in Relational form and what you want as RDF representation

<Souri> rel schema and the corr rdf schema

<angela_UNITN> sorry the connection is terrible...

Ahmed: Adjourn early

<Souri> regrets for next week

<juansequeda> ericP, do you have the ddl of the usecase?
