14:49:41 <Zakim> -mhausenblas 14:51:44 <Li_Ding> :getting common vocabulary for describing data right is more important than publishing data in RDF 14:53:01 <Li_Ding> : if keep the provenance of data all the way through, we can better maintain transparency and support people to connect the visualization results to the original source 14:53:41 <Li_Ding> : it is very useful to connect the source of original data 14:54:41 <Li_Ding> Ding: it is useful in the demo to mention the data used in the demo 14:55:56 <Li_Ding> : we should try to make sure dataset description always openly accessible by the public 14:56:13 <Li_Ding> ding: data.gov has defined a set of vocabulary for dataset 14:56:15 <Li_Ding> http://www.data.gov/glossary 14:56:46 <Li_Ding> : in order to have tools working, known the metadata of dataset is very important 14:56:57 <johnlsheridan> johnlsheridan has joined #egov 14:56:58 <sandro> sandro: I think one compelling advantage of Linked Data is that we can maintain provenance, so folks seeing conclusions can easily track it back to sources. If we do that right, we hopefully free people to publish data at various levels of confidence, comfortable in the knowledge that the metadata (like confidence level) they provide will not be lost. 14:57:42 <edsu> Li_Ding: is the description at http://data-gov.tw.rpi.edu/wiki/Dataset_92 not fully represented in the triples you get back the rdf feed http://data-gov.tw.rpi.edu/wiki/Special:ExportRDF/Dataset_92 14:58:04 <Li_Ding> : We hope the machine-understandable vocabulary for dataset metadata can help better demo/tool development, and we may consider use dubline core, void ontology 14:58:34 <sandro> rrsagent, make record public 14:58:39 <johnlsheridan> we are looking to use void for data.gov.uk linked data work 14:58:45 <edsu> Li_Ding: are you in convo with richard and michael about what they are working on w/r/t vocab for datasets? 14:58:52 <Li_Ding> DING: yes, the 80% metadata is from data.gov, and when we generate RDF, we put some extra annotations 14:58:57 <sandro> cory: Let's think about how to leverage all this great work.... 14:59:00 <Li_Ding> yes 14:59:10 <edsu> Li_Ding: sweet 15:00:04 <Zakim> -Ken_Fischer 15:00:05 <Zakim> -Sandro 15:00:05 <Zakim> -Cory 15:00:07 <Zakim> -Li_Ding 15:00:07 <Zakim> T&S_EGOV(LD Demo)8:00AM has ended 15:00:08 <Zakim> Attendees were +1.518.276.aaaa, Sandro, Cory, +1.703.938.aabb, Ken_Fischer, mhausenblas, Li_Ding, edsu 15:00:13 <Li_Ding> Ding: yes, I have been work with michael on their void ontology development, and we've made some changes on the dataset, e.g. switching from DC to DCTERMS 15:00:23 <edsu> Li_Ding: cool 15:00:36 <Li_Ding> I will be happy to continue work with Michael on the dataset vocabulary design 15:00:37 <edsu> Li_Ding: not sure if you saw my question about the rdf for that dataset 92 for example 15:00:58 <edsu> Li_Ding: is there a url for the rdf/xml representation of http://data-gov.tw.rpi.edu/wiki/Dataset_92 ? 15:01:27 <Li_Ding> edsu: the dataset 92 RDF description is from the other URI. We found that SMW has a little bit problem handling our URI naming convention. 15:01:28 <edsu> Li_Ding: i followed the 'RDF feed' icon link, but it didn't seem to return all the data that i see described in the page? 15:01:35 <Li_Ding> http://data-gov.tw.rpi.edu/vocab/Dataset_401 15:01:57 <edsu> Li_Ding: so looking at that HTML representation is there a way of discovering, and following nose to the rdf/xml? 15:02:03 <Li_Ding> yes 15:02:11 <Li_Ding> if you search for owl:sameAs 15:02:17 <Li_Ding> you should find the link 15:02:30 <Li_Ding> Owl:sameAs http://data-gov.tw.rpi.edu/vocab/Dataset_92 + 15:02:38 <Li_Ding> that is as the bottom of the html page 15:02:44 <edsu> ahh 15:02:50 <edsu> so scrape it 15:03:04 <Li_Ding> we are working on improving the interface for better UI, 15:03:20 <Li_Ding> you should see improvement soon 15:03:33 <edsu> ok -- my one suggestion would be to add at least a <link rel ...> for the rdf/xml 15:04:44 <edsu> <link rel="alternate" type="application/rdf+xml" href="http://data-gov.tw.rpi.edu/vocab/Dataset_92" /> 15:06:26 <edsu> i guess you guys have talked about using rdfa to make the rdf available? 15:07:34 <edsu> i realize you are probably bound by whatever semantic media-wiki currently supports, but if you have spare grad students that could get rdfa support into semantic media wiki that would be awesome :-) 15:08:02 <edsu> building on what ben andn others at creative commons started a few years ago http://wiki.creativecommons.org/RDFa_Support_for_Semantic_Media_Wiki 15:08:33 <edsu> sorry, for blathering on like this -- i'm basically just really excited about the work you guys are doing with the data.gov data :-) 15:10:48 <Li_Ding> thanks 15:11:18 <Li_Ding> we have already get RDFa embedded in our dataset page 15:12:14 <Li_Ding> if you open the source page, you should see something like the following 15:12:18 <Li_Ding> <div id='RDFa' about='http://data-gov.tw.rpi.edu/wiki/Dataset_92' xmlns:wiki_1='http://data-gov.tw.rpi.edu/w/index.php/'xmlns:wiki_1_property='http://data-gov.tw.rpi.edu/w/index.php/Property:'xmlns:wiki_1_category='http://data-gov.tw.rpi.edu/w/index.php/Category:' typeof='wiki_1_category:Dgtwc:Dataset' typeof='wiki_1_category:Converted Dataset' typeof='wiki_1_category:Data.gov Dataset'> 15:12:20 <Li_Ding> <a href='wiki_1:Executive_Office_of_the_President' rel='wiki_1_property:92/agency'></a> 15:12:21 <Li_Ding> <div property='wiki_1_property:92/agency_data_series_page' content='http://www.data.gov'></div> 15:12:23 <Li_Ding> <div property='wiki_1_property:92/agency_program_page' content='http://www.data.gov'></div> 15:12:31 <edsu> yeah, i see some 15:12:41 <Li_Ding> I can discuss RDFa usage in the next telecon 15:14:34 <edsu> i see this, with the rdfa highlighter: http://inkdroid.org/tmp/data-gov-tw-screenshot.png 15:14:41 <edsu> Li_Ding: that would be great 15:15:50 <Li_Ding> thanks for the screen shot 15:17:56 <Li_Ding> Li_Ding has joined #egov # SPECIAL MARKER FOR CHATSYNC.
