2. Roll Call:

  • welcome and intro of new member(s) (if applicable)

3. Key discussion:

3.1 Review of last meeting's decision and action items

  • 2013.06.25: we reached consensus that we will be formalizing the API as discussed using the (OMG) Interface Definition Language (IDL) (v3.5)
    • Till Mossakowski will work on formalizing the API agreed on (ref.)

3.3 scheduling ... (ref. "7. Any Other Business" below)

  • decide on agenda for the next 2 meeting Jul-23 & Jul-30 (before we take a break in Aug-2013) ... and then Sep-3 and Sep-10

4. Prior Discussions:

4.1 Discussion: tactically, what shall we be doing differently in the next 6 to 12 months

  • Focused discussion on the tactics and action plans that will help put the recently refined OOR Strategy in place

... to provide synergies for all.

4.2 Setting the metrics - what does "success" look like

4.3 Action planning for "content drive" (getting people to upload ontologies) ... (deferred discussion of this item)

  • (discussion 2011.05.06):
    • an adopted Architecture & API is definitely crucial, but that's not all
  • All team members are encouraged to mull over how we can get to that state effectively
    • in particular ... how do we make this a "successful" community-driven, open source project!?
  • (discussion 2011.08.07) ...
    • ref. IAOA Committee and SIG session at FOIS (2012.07.25) discussion:
      • IAOA Ontology Registry and Repository Committee to put focus on contents
      • getting FOIS papers to be submitted with cited ontologies and their metadata, and have those ontologies hosted on OOR
  • 4.5 OOR instances OOR: status update and coordination ... (deferred discussion of this item)
  • OOR: sandbox, devbox, test-instance, socop, colore, ontohub, ornl-daac, mmi-orr, new ncbo-appliance, ... status update and coordination
  • 4.6 Getting us to a stage when we can run a OOR-production box ... (deferred discussion of this item)
    • we need a gatekeeping/policy module in place - [KenBaclawski]
  • 4.7 Renewed OOR tactics (as agreed during the 2013.06.18 meeting) - there is general consensus we would change to a more bottom-up approach (rather than the "top-down" approach we have been taking ...
    • we will allow each oor node project to develop (colore, ontohub, socop, oor public instance, etc.) on their own, and coordinate the "team" effort through the use of a shared set of metadata, API and the UI (e.g. how people download (or even upload) ontologies, etc.)
    • The key is to ensure that each of the ontology repository projects in OOR are interoperable from the software perspective, uniform in the GUI, and they use a shared approach to ontology metadata
    • we will make oor.net to be an ontology registry, which then links to the ontologies in the actual ontology repository where the ontology is described
    • actions will be focused on developing three things (hopefully within the next 3 months): the set of metadata, the API, and some shared thoughts on the UI
    • after that, we will focus on building up content with each OOR node tackling the domain(s) they are best with

[6:59] Peter P. Yim: Welcome to the

OOR "Hackathon" Session (n.02) - Tue 2013_07_16

  • Session Topic: The "OOR-Ontohub-Gatekeeper API - II" Hackathon

[7:03] anonymous morphed into Aleksandra Sojic

[7:02] Peter P. Yim: Till: ref.

http://ontolog.cim3.net/cgi-bin/wiki.pl?OOR/ConferenceCall_2013_07_16#nid3VKT -

https://github.com/ontohub/ontohub/blob/specifying179_formalizing_ontology_repository_service/api/ontology.idl

[7:13] Ken Baclawski: The idlj compiler converts from IDL to Java. It is a standard tool in any Java

Development Kit (jdk) so if you have Java installed you should also have idlj.

[7:15] Ken Baclawski: The idlj compiler is handy for checking the IDL syntax. I used idlj to convert

an IDL to Java, and then it is relatively easy to convert to WSDL.

[7:09] Till Mossakowski: [action] we will set up a new github repository, only for the API

[7:07] Ken Baclawski: My GitHub name is "baclawski."

[7:15] Peter P. Yim: when this OOR-API github instance is up, please subscribe me too - my github

username is "yimpp"

[7:23] Till Mossakowski: [action-completed] new repository at

https://github.com/ontohub/OOR_Ontohub_API ... both Ken and Peter are subscribed now

[7:11] Todd Schneider: What happened to the use of instances of the metadata ontology as the function

parameter?

[7:30] Todd Schneider: The API for 'selecting' is effectively a query mechanism, the front end to the

user. The other side of this is the 'retrieving' of the requested or queried data. For the front end

of selecting or querying for ontologies (or metadata about them) use of an instance of the metadata

ontology should be used as the single parameter for the 'select' method. The particular parameters

of interest would be represented by non-null values (in the ontology instance). This simplifies the

API and overall architecture (but moves complexity to the parsing of the ontology instance). The

retrieval (or return values) of the 'selected' results would make use of federate identifiers.

[7:35] Till Mossakowski: @Todd: the single parameter should be a struct

[7:39] Till Mossakowski: add-on to Todd's message: the user should be able to select whether the

method call should just deliver ids (compact representation) or all the metadata (say, as an XML

tree), or even the whole ontology/ies (can become very large)

[7:42] Todd Schneider: Till, good point about a parameter to specify return value(s).

[7:42] Till Mossakowski: IDL methods are synchronous by default. If the execution of a method takes

very long, it should be made asynchronous (keyword: oneway).

[7:33] Ken Baclawski: I have posted the Gatekeeper API in gatekeeper.idl. This is accepted by idlj.

[7:44] Peter P. Yim: Till+Ken: now online at github:

... OOR_Ontohub API - https://github.com/ontohub/OOR_Ontohub_API/blob/master/ontology.idl ... and,

... OOR_Gatekeeper API - https://github.com/ontohub/OOR_Ontohub_API/blob/master/gatekeeper.idl

[7:47] Till Mossakowski: Daniel will work on a new iteration of the API, and test it with idlj. He

will also integrate the gatekeeper API as a module. Once this iteration is there, Daniel will send a

mail, and others can contribute through github.

[7:47] Peter P. Yim: [consensus] we will leave these two API's as separate modules - OOR-Ontohub-API and

OOR-Gatekeeper-API

[7:48] Peter P. Yim: (for the lower level development work) we should use the [oor-dev] mailing list

[7:48] DanielCoutoVale: my e-mail is danielvale [at] uni-bremen.de

[7:49] Peter P. Yim: [action] I will subscribe everyone present at today's session to the [oor-dev] list

(in case he/she isn't yet)

[7:50] List of members: Aleksandra Sojic, DanielCoutoVale, Ken Baclawski, Mike Bennett, Oliver Kutz,

Peter P. Yim, Till Mossakowski, Todd Schneider

[7:49] Peter P. Yim: ^[action-completed] ... done subscribing everyone here onto the [oor-dev] list!

[8:04] Todd Schneider: Sorry; Have to go. Thank you.

[8:01] Till Mossakowski: we just need to start with the "upper level" of the classification.

People can later add finer distinctions. The classification system should be itself an OWL ontology,

hosted at OOR-Ontohub.

[7:53] Ken Baclawski: Another source of ontology classification (or perhaps properties of an

ontology) is the Ontology Summit 2007 http://ontolog.cim3.net/cgi-bin/wiki.pl?OntologySummit2007

[7:57] Till Mossakowski: United Nations Standard Products and Services Code: http://www.unspsc.org/

[8:03] Peter P. Yim: @Ken - UNSPSC codeset can be downloaded at: http://www.unspsc.org/codeset-downloads

... (generally cost $100) the pdf's are free

[8:06] Mike Bennett: Prescriptive v Descriptive ontologies

[8:07] Till Mossakowski: follow up to Ken/2007 summit: ontologies may be classified as descriptive or prescriptive

[8:07] Mike Bennett: (that is extensional v intensional definitions in the ontology)

[8:08] TillMossakowski-KenBaclawski: The Ontology Summit 2007 Communique is

at: http://ontolog.cim3.net/cgi-bin/wiki.pl?OntologySummit2007_Communique

[8:11] Peter P. Yim: upcoming meetings: OOR-hackathon n.03 - Tue Jul-30 ... break in Aug-2013

... OOR-hackathon n.04 - Tue Sep-10
