bhyland: no comments to other groups?
... let's focus on main agenda

Noteworthy Gov't LOD in 2012

bhyland: thanks for the information you sent
... any other comments/suggestions
... any volunteer to talk about the projects
... and also the origin of that project
... research project, commercial, etc
... how the project came about
... who wants to start ....

<olyerickson> The whole "bathing"/"swimming" thing was confusing ;)

bhyland: gld projects in last 6-10 months
... important to show these projects in Semtech

BartvanLeeuwen: stuff fire department related stuf
... you can see on the web
... http://kasabi.com/dataset/brandweer-amsterdam-amstelland-dispatch-messages

Noteworthy LOD projects - Bart & the Amsterdam Fire Dept

BartvanLeeuwen: we are going to extend the information ...

<bhyland> Scribe: Tinagheen

BartvanLeeuwen: ...side effect - what we tried to do was have statistics on what probabilities of fire
... were in certain parts of Amsterdam
... how did we get there
... used Linked Data to connect several sources within FD together
... so why not put data on internet as structured data?

<Mike_P> I can talk about what U.S. EPA is up to

bhyland: who handle maintenance of data

BartvanLeeuwen: use kasabi

<rreck> i never find any easter eggs in zakim and i cant believe there arent any.

<gatemezi> Kasabi URL: http://kasabi.com/

bhyland: re: kasabi - free to host your data. Still working out business model

<BartvanLeeuwen> http://kasabi.com/dataset/brandweer-amsterdam-amstelland-dispatch-messages

<boris> http://kasabi.com/dataset/brandweer-amsterdam-amstelland-dispatch-messages

<Mike_P> hard to hear you bernadette

<csarven> World Bank Linked Data: http://worldbank.270a.info/

csarven: World Bank Linked Data effort

Noteworthy gov't LOD projects: World Bank LD

csarven: technical background - part of thesis at DERI
... grabbed data sets from World Bank
... transformed JSON to RDF
... publish them, SPARQL endpoint for the site
... several datasets, some overlap
... linked data sets as best he could, but more linking can be done
... interlinking with other data sets
... dbpedia and eurostat
... hosted at DERI

<cgueret_work> +q

some datasets are in good condition (development indicators for ex.)

scribe: World Bank financial dataset - needed some clarification/clean up
... using PHP
... Paget - for content negotiation, templating

<gatemezi> @csarve: what politic did you use for the URIs ?

<olyerickson> I believe csarven said he was also using Fuseki http://bit.ly/LHXUAq

scribe: Moriarty - for SPARQL
... this is not a collaboration with World Bank and is not endorsed by World Bank

bhyland: you are using World Bank content and they are happy to answer your questions

<cgueret_work> -q

bhyland: do you have a take on where World Bank is on the 5-star linked data scale, in terms of management and capability

<cgueret_work> bhyland is asking exactly what I wanted to ask... :)

csarven: not sure
... financial data sets can be accessed through Socrata

<MartinKaltenb> they (WB) will be soon on 5 star data with their thesaurus as far as I know

csarven: written in XML, no namespaces worked out
... all open as far as he knows
... just want attribution (World Bank)
... thesis is investigating how much interlinking can be done

bhyland: similar effort done at EPA last year
... student did mashup
... no common vocabulary to link it all together
... but still a valuable exercise/experience

<cgueret_work> +1 to bhyland

bhyland: especially to share with other people in a blog post
... tools used, problems encountered, solutions, etc.

csarven: yes, will be part of thesis
... lessons learned, how he solved problems he faced

<bhyland> Here is a link to the US HHS + US EPA LOD effort last year, in a "lessons learned & how I solved problems" perspective, see http://www.data.gov/communities/node/116/blogs/6170

csarven: will be finished in mid-July

<olyerickson> LOL!

boris: are you using RDF data cube vocab?
... do you have observations or other information?

csarven: country code list, currency code list
... SDMX

boris: ISO code lists?

csarven: yes, majority is coming from original data - not manipulated
... manipulation is normalization

<MartinKaltenb> we use geonames ontology

bhyland: is there a defacto standard for currecy/country codes?

<bhyland> @MartinKaltenb, right, that is what we've used in past

boris: we used ISO standards - transformed into RDF, but did not publish to a website

<mhausenblas> Related: http://www.qudt.org/

<boris> http://mayor2.dia.fi.upm.es/oeg/index.php/en/ontologies/99-hrmontology

bhyland: we should be using a common vocab for this

<Biplav> FAO has a good list of country codes.

<mhausenblas> and more via http://linkedmodel.org/ (OWL Ontologies and SKOS Vocabularies for Linked Models of Industry and Government Standards)

gatemezi: what policy did csarven use for generating URIs?

<bhyland> Ghislain asked "what URI policy did you use?"

<bhyland> how did you generate URIs Sarven?

<Biplav> FAO: see http://www.fao.org/countryprofiles/iso3list.asp

<gatemezi> http://labs.mondeca.com/dataset/lov/search/#s=currency

csarven: all URIs needed to be resolvable, no fragments
... want to publish everything as human and machine readable
... should be accessible down to observation level

US EPA LOD

Mike_P: EPA converted 3 core data sets
... Linked Data is coming out of Data Standards Branch Office of Environmental Standards

use registries for chemicals

<bhyland> Mike_P in Office of Environmental Information at EPA. Includes facilities & chemicals that the EPA regulates.

<MartinKaltenb> remark to country codes: I think ADMS of ISA gives recommendations also here - Phil should know more about this...

scribe: registries map differences

<bhyland> Different programs & legislation call chemicals different names, so they need to be mapped

scribe: in naming
... facility and chemical name registries

<bhyland> Flagship data that EPA publishes include emissions of chemical (carcinogens) into the air, water & land … called Toxic Release Inventory (TRI)

scribe: do not have a hosting solution at this time, planning to use Kalimachus

<bhyland> Hosting on the cloud and working on system security plan.

<olyerickson> RE countries, it's important to link a canonical URI to a canonical/common version of label (e.g. DBPedia common name)

<olyerickson> ... we're extending our Instance Hub to provide that

<rreck> with something like owl sameAs?

<olyerickson> @rreck was that q for me? Answer is yes

<rreck> yes, it was for you

<rreck> i am not in the call because i am onsite

<MartinKaltenb> would you like to know about reegle / nrel?

MartinKaltenb: a few words about reegle

Reegle & use by NREL by MartinKaltenb

MartinKaltenb: Clean energy platform
... built LOD platform called ...?
... blog post is available to explain strcuture

<olyerickson> But is ADMS providing URs for Countries? That is the key missing piece: country URIs <=> variants of country names

<bhyland> Main goals: build country profiles and test LOD principles for stitching together data

<bhyland> Per Martin Kaltenböck, Clean Energy data from Reegle, see see http://data.reegle.info/ for data, manuals and endpoint as 5 star LOD for re-use. See blogpost on same, http://blog.semantic-web.at/2012/04/13/reegle-info-linked-open-energy-data-cloud/

MartinKaltenb: can get expanded profiles of countries about clean energy
... goals: data integration, metrics

<bhyland> Goals: Better data integration & achieve network effect

MartinKaltenb: wanted to open energy information to the community

<bhyland> … reduce duplication of data

<bhyland> … saves operational costs

MartinKaltenb: data enrichment
... partners pull in data from each other to enhance data on their own platforms/ data integration
... underlying triple store Virtuoso

<bhyland> Tools used: PoolParty, Virtuoso for RDF store

MartinKaltenb: using D2R server

<bhyland> D2R project, joint project from Free Univ of Berlin and DERI.

<boris> SCOVO

<rreck> do you need d2r?

MartinKaltenb: for statistical data use scovo

<mhausenblas> Note that SCOVO is deprecated. shouldn't be used any more. Says the main guy behind SCOVO ;)

mhausenblas: encouraging people to use DataCube
... XDMS compliant

bhyland: how is this project funded?

MartinKaltenb: nrel funded by US
... public/private partnership

<bhyland> A web developer on the NREL.org project is Jon Weers who gave a talk on OpenEI: LOD Success Stories.

Announcements

<MartinKaltenb> that could be interesting too: http://www.slideshare.net/reeep/lod-workshopbest-practiceopeneiandreegle

Biplav: AAAI Conference July 22-23
... colleague presenting at SemTech

<MartinKaltenb> European Data Forum, 6-7 June Copenhagen: http://www.data-forum.eu/

<cgueret_work> is it nrel.org or nrel.gov ?

<bhyland> There is also a semantic start-up competition happening at SemTech West in June, see http://semanticweb.com/semantic-start-up-contenders-announced_b29248#more-29248

<Biplav> Rosario U. Sosa from IBM Watson Research will talk about SCRIBE at Semtech (Biplav's colleague)

<MartinKaltenb> SWC talk at SemTecBiz: http://semanticweb.com/poolparty-powertagging-to-be-published-at-semtechbiz-sf_b28827

<olyerickson> unmute me

<mhausenblas> cheers and bye - cya!

<olyerickson> Have a great one!

<BartvanLeeuwen> thx

<Yigal> bye
