Welcome to the OpenOntologyRepository: OOR Team Conference Call - Fri 2010-11-19 Session Title: "(Post-BioPortal fork) OOR Architecture and API - Take-II" Session Co-chairs: KenBaclawski (NEU) & MichaelGruninger (U of Toronto) Panelists: * KenBaclawski (NEU) + ToddSchneider (Raytheon) * AldoGangemi + AlessandroAdamou (STLab, Rome) * JouniTuominen + KimViljanen (Aalto U, Finland) * MathieuDaquin (NeOn, Open University, UK) * EricChan (ICOM) please refer to details on the session page at: http://ontolog.cim3.net/cgi-bin/wiki.pl?OOR/ConferenceCall_2010_11_19 . anonymous morphed into JouniTuominen JouniTuominen: Peter: are you controlling the presentation slides in the shared vnc and the presenter tells everyone (including you) to advance on slides, or how does it work? PeterYim: yes ... just tell me when to advance slides ... and call out the slide number as well JouniTuominen: Peter: ok, thanks anonymous morphed into MichaelGruninger anonymous1 morphed into MyCoyne KimViljanen: hello MyCoyne: Where would I be able to obtain the presentation? MyCoyne: Does anyone has a problem with audio: the speaker voice is very faint PeterYim: I can hear them ok ... Ken seems to be fading in and out a bit, though KimViljanen: http://www.onki.fi KimViljanen: LOOS (workshop in ESWC2009): http://www.slideshare.net/digikim/ores2010-linked-openontologyservices20100528slideshare MyCoyne: Questions for LOOS: (1) does LOOS use any underline grid or enterprise service bus for its registration? (2) Is there any API allows for merging of ontologies? (3) is LOOS available for dowloading trials? anonymous morphed into BartGajderowicz PeterYim: very well thought through presentation, Jouni and Kim ... thank you! KimViljanen: Peter: thanks for the positive feedback above ToddSchneider: ONKI seems to provide more capabilities than envisioned by the OOR KimViljanen: Todd: e.g.? ToddSchneider: Annotation KimViljanen: but the main question we wanted to present is: is the OOR application needed or the APIs to connect existing ontology repositories? KimViljanen: ok, so we are now planning the OOR Architecture (global) _and_ the Architechture of the reference implementation KenBaclawski: Yes, Kim, that is the idea. ImmanuelNormann: @ONKIs: I like the openess in your proposal w.r.t. technical solutions like REST vs. SOAP, different programming languages, etc. But I get the impression that you are committed to OWL-ontologies only. How open are you w.r.t. to different ontology languages? KimViljanen: Immanuel: our idea in LOOS was to support "simple" ontologies in the spirit of SKOS. that is, we think there are common features shared among different ontology languages such as "concepts have labels" KimViljanen: Immanuel: and for example if the user is searching for "fish", the user can then continue using the specific ontology repository for ontology specific functionalities, which may be ontology language dependent, require inference etc ImmanuelNormann: as said before I like the openess w.r.t to technical means to implement an OOR. But at some point we need to specify some service APIs - and finally we have to commit to some format to define service APIs. One option would be WSDL. What is your opinion? KimViljanen: I would support many: e.g. in ONKI we provide both a REST, Web Service and JavaScript API --- the last two automatically created from the same java classes KimViljanen: (which mean WSDL can be used describing the APIs) MyCoyne: Is ICOM a licensed product from Oracle? PeterYim: ICOM is an OASIS Technical Committee (TC) ... it is being developed as an open standard MyCoyne: Thanks, Peter. This is very helpful. ImmanuelNormann: @Kim: REST, SOAP, Java, JavaScript, ..., are rather specific language specific solutions. I think it wouldn't make sense to specify e.g. one API in two or more languages. I was rather thinking about programming language independent spec like e.g. IDL is used at W3C for specifying the DOM model, or WSDL for web services or WADL for the REST world. So is WSDL your favourite? KimViljanen: @Immanuel: well... typically we have made so simple APIs that just writing them in a (free form) human readable document has been enough KimViljanen: @Immanuel: btw, we forgot to say in our presentation that we were discussing whether OOR could initiate / produce a W3C recommendation of this OOR API issue, as a member contribution or something (not fully familiar with the W3C procedures on this) PeterYim: @Kim - International standardization is definitely a medium to long term goal ... whether it is W3C or OASIS or ISO, as the SDO (standard development organization) infrastructure we should leverage would depend on other pragmatic factors (e.g. who is on the team, experience of the members with the particular SDO process, expedience, which approach can best help us reach our ultimate goals ... etc.) anonymous morphed into MattHettinger MikeBennett: Standardization of metadata about ontologies - agreed, very important. There are a number of common problems currently implemented in different ways by different ontologies. We could start by cataloguing these. Provenance is one such. KimViljanen: could the first step for aligning the ontologies be that each of us provides a document on their APIs (I suppose everybody have a somekind of a document existing), to get an overview ToddSchneider: Yes. I'd suggest placing the artifacts on the OOR Architecture Wikipage ToddSchneider: If possible, UML models would be optimal. KimViljanen: [on Ken's remark that BioPortal (on which the OOR sandbox is running now) features about 126 methods] (ONKI LOOS API has ca. 10-15 methods) KenBaclawski: Here is the suggestion for followup action items: 1. Post your artifacts on the OOR Architecture wikipage, 2. Review the artifacts on the wikipage, 3. Schedule a new meeting. KenBaclawski: Those who were not at the Take I architecture meeting should review that wikipage. PeterYim: that Architecture & API (take-1) meeting would be at: http://ontolog.cim3.net/cgi-bin/wiki.pl?OOR/ConferenceCall_2010_10_15 KenBaclawski: Everyone should create their own subpage of the architecture wikipage. KimViljanen: thanks for an inspiring meeting! YuriyMilov: Thanks for the great presentations PeterYim: nice session ... thank you! PeterYim: -- session ended: 8:06am PST -- //
