15:07:09 <soeren> that's the triplify presentation
15:07:24 <hhalpin> +1 to skipping telecon next week.
15:07:47 <hhalpin> Then we also get to reconfigure time today.
15:07:55 <mhausenblas> yes, indeed

15:10:11 <hhalpin> Notes "The mapping language MUST define the set of relational algebra to be supported in the first release. This set to be supported SHOULD be as complete as possible and be defined as soon as possible after the WG official launch."
15:10:35 <hhalpin> I expect that we should have Marcelo give a presentation on his work on formal semantics ASAP after we're done with the implementation overviews.
15:11:04 <mhausenblas> T+4: Requirements and Use Cases for the RDB2RDF Mapping Language (R2RML)
15:12:58 <mhausenblas> Topic: Presentation of Triplify
15:13:16 <mhausenblas> slides see http://www.w3.org/2001/sw/rdb2rdf/wiki/images/6/6d/Triplify.pdf
15:13:34 <Souri> About the requirements 'SHOULD' portion: What is "human-readable"? Is SQL query human-readable?
15:13:49 <mhausenblas> soeren: our group works on couple of tools (DL Learner, etc.) as well as onTriplify
15:14:07 <mhausenblas> slide 2
15:14:14 <mhausenblas> TriplifyBig Picture
15:14:21 <mhausenblas> slide 3
15:14:28 <mhausenblas> motivation
15:14:47 <mhausenblas> many DB-backed applications
15:15:16 <mhausenblas> idea: when we're able to RDFise the content of these DB, we gain quite a bit - Web of Data
15:15:49 <mhausenblas> most of the tools are OSS, should be easy to integrate
15:15:55 <mhausenblas> slide 4
15:16:26 <mhausenblas> configure once, use often
15:16:33 <mhausenblas> slide 5
15:16:54 <mhausenblas> solution: uses SQL to transform
15:17:30 <mhausenblas> extends SQL with some syntactic constructs 
15:17:51 <mhausenblas> maps URI patterns to set of SQL patterns
15:18:09 <mhausenblas> according to the Linked Data principles
15:18:14 <mhausenblas> slide 6
15:18:30 <mhausenblas> Ashok: will you talk about the extensions?
15:18:34 <mhausenblas> soeren: yes
15:18:42 <mhausenblas> soeren: just some conventions, actually
15:20:15 <mhausenblas> soeren: few tables anyway, no automatic generation, hence
15:21:04 <mhausenblas> ... conventions, such as first col must be an ID, the col name should refer to RDF properties
15:21:41 <Souri> q+
15:21:58 <mhausenblas> ack Souri 
15:22:15 <mhausenblas> Souri: conceptual mapping or materialising?
15:22:20 <mhausenblas> soeren: view
15:22:25 <mhausenblas> slide 7
15:22:49 <mhausenblas> soeren: here is an example mapping a WP blog post
15:23:06 <mhausenblas> http://blog.aksw.org/triplify/post/(xxx)
15:23:31 <mhausenblas> SELECT id, post_authorAS 'sioc:has_creator->user', 
15:23:31 <mhausenblas> post_title AS 'dc:title', 
15:23:31 <mhausenblas> post_content AS 'sioc:content', post_date AS 
15:23:32 <mhausenblas> 'dcterms:modified^^xsd:dateTime‘, 
15:23:32 <mhausenblas> post_modified AS 'dcterms:created^^xsd:dateTime' 
15:23:32 <mhausenblas> FROM posts 
15:23:33 <mhausenblas> WHERE post_status='publish‘ (ANDid=xxx) 
15:25:36 <Souri> q+
15:26:21 <mhausenblas> ack Souri 
15:26:49 <mhausenblas> Souri: we took the same approach
15:27:14 <mhausenblas> Souri: our work was so far only internally
15:28:01 <mhausenblas> Souri: there are two approaches to address the datatype
15:28:48 <mhausenblas> soeren: needed to overwrite the default (Triplify supports both)
15:29:14 <mhausenblas> Souri: I think we need a consistency check - explicit might be more benfical
15:29:36 <mhausenblas> slide 8
15:30:08 <mhausenblas> shows the actual RDF conversion
15:30:10 <mhausenblas> slide 9
15:30:22 <mhausenblas> summarises the implementation of Triplify
15:30:38 <mhausenblas> design principle is KISS
15:30:49 <mhausenblas> no new mapping language (SQL is used)
15:31:14 <mhausenblas> available for popular languages
15:31:26 <mhausenblas> works with most DBs
15:32:08 <mhausenblas> rrsagent, draft minutes
15:32:08 <RRSAgent> I have made the request to generate http://www.w3.org/2009/10/29-RDB2RDF-minutes.html mhausenblas
15:32:18 <mhausenblas> slide 10
15:32:31 <mhausenblas> an example of an WP blog configuration
15:32:35 <mhausenblas> nine queries
15:33:56 <mhausenblas> slide 11
15:34:08 <mhausenblas> we offer a configuration repository
15:34:19 <mhausenblas> slide 12
15:34:23 <mhausenblas> slide 13
15:34:27 <mhausenblas> two extensions
15:34:32 <mhausenblas> a temporal extension
15:34:51 <mhausenblas> address the 'when to crawl data'
15:34:53 <mhausenblas> slide 14
15:35:31 <mhausenblas> shows how this works in Triplify 
15:36:34 <mhausenblas> Michael: would be good to know the update voc URI
15:36:39 <mhausenblas> slide 15
15:37:09 <mhausenblas> LOD update log generation
15:37:37 <Souri> LOD means ???
15:37:39 <mhausenblas> slide 16
15:37:43 <mhausenblas> Linked Open Data
15:37:47 <mhausenblas> Spatial Extension
15:37:51 <Souri> Thanks.
15:37:54 <mhausenblas> yw
15:37:58 <mhausenblas> see linkeddata.org
15:38:46 <mhausenblas> soeren: used the spatial extension to create linked data version of  OpenStreetMap
15:39:33 <mhausenblas> slide 17
15:39:50 <mhausenblas> example from http://linkedgeodata.org/
15:41:49 <Souri> q+
15:42:36 <mhausenblas> ack Souri 
15:42:50 <mhausenblas> Souri: which query interface do you support?
15:42:55 <mhausenblas> soeren: based on URIs
15:43:41 <mhausenblas> skip to slide 19
15:43:51 <mhausenblas> RDB2RDF tool comparison
15:44:06 <mhausenblas> Triplify, D2R and Virtuoso views
15:45:42 <mhausenblas> slide 20
15:46:01 <mhausenblas> soeren: Triplifysupports the “long tail” of deployed Web applications 
15:46:51 <mhausenblas> soeren: that's it - questions?
15:47:17 <soeren> http://www2009.eprints.org/63/
15:47:59 <mhausenblas> Ashok: license?
15:48:09 <mhausenblas> soeren: it's OSS
15:48:51 <mhausenblas> soeren: more background on Triplify see WWW paper above, will send to list and update Wiki
