OpenOntologyRepository: OOR "Hackathon" Session (n.02) - Tue 2013_07_16     (1)

Session Topic: The "OOR-Ontohub-Gatekeeper API - II" Hackathon     (1A)

Session Co-chairs: KenBaclawski & TillMossakowski     (1B)

This is the 2nd session in a series of regular "hackathon" activities for the OOR team. The plan is to devote one meeting a month to intense coding (or other low level development) work.     (1C)

  • Dial-in:     (1D4)
    • Phone (US): +1 (206) 402-0100 ... (long distance cost may apply)     (1D4A)
    • Skype: joinconference (i.e. make a skype call to the contact with skypeID="joinconference") ... (generally free-of-charge, when connecting from your computer ... ref.)     (1D4B)
      • when prompted enter Conference ID: 141184#     (1D4B1)
      • Unfamiliar with how to do this on Skype? ...     (1D4B2)
        • Add the contact "joinconference" to your skype contact list first. To participate in the teleconference, make a skype call to "joinconference", then open the dial pad (see platform-specific instructions below) and enter the Conference ID: 141184# when prompted.     (1D4B2A)
      • Can't find Skype Dial pad? ...     (1D4B3)
        • for Windows Skype users: Can't find Skype Dial pad? ... it's under the "Call" dropdown menu as "Show Dial pad"     (1D4B3A)
        • for Linux Skype users: please note that the dial-pad is only available on v4.1 (or later; or on the earlier Skype versions 2.x,) if the dialpad button is not shown in the call window you need to press the "d" hotkey to enable it. ... (ref.)     (1D4B3B)
  • Discussions and Q & A:     (1D5)
    • Nominally, when a presentation is in progress, the moderator will mute everyone, except for the speaker.     (1D5A)
    • To un-mute, press "*7" ... To mute, press "*6" (please mute your phone, especially if you are in a noisy surrounding, or if you are introducing noise, echoes, etc. into the conference line.)     (1D5B)
    • we will usually save all questions and discussions till after all presentations are through. You are encouraged to jot down questions onto the chat-area in the mean time (that way, they get documented; and you might even get some answers in the interim, through the chat.)     (1D5C)
    • During the Q&A / discussion segment (when everyone is muted), If you want to speak or have questions or remarks to make, please raise your hand (virtually) by clicking on the "hand button" (lower right) on the chat session page. You may speak when acknowledged by the session moderator (again, press "*7" on your phone to un-mute). Test your voice and introduce yourself first before proceeding with your remarks, please. (Please remember to click on the "hand button" again (to lower your hand) and press "*6" on your phone to mute yourself after you are done speaking.)     (1D5D)
    • instructions: once you got access to the page, click on the "settings" button, and identify yourself (by modifying the Name field from "anonymous" to your real name, like "JaneDoe").     (1D6A)
    • You can indicate that you want to ask a question verbally by clicking on the "hand" button, and wait for the moderator to call on you; or, type and send your question into the chat window at the bottom of the screen.     (1D6B)
    • thanks to the folks, one can now use a jabber/xmpp client (e.g. gtalk) to join this chatroom. Just add the room as a buddy - (in our case here) ... Handy for mobile devices!     (1D6C)
  • Shared-screen support (VNC session), if applicable, will be started 5 minutes before the call at:     (1D7)
    • view-only password: "ontolog"     (1D7A)
    • if you plan to be logging into this shared-screen option (which the speaker may be navigating), and you are not familiar with the process, please try to call in 5 minutes before the start of the session so that we can work out the connection logistics. Help on this will generally not be available once the presentation starts.     (1D7B)
    • people behind corporate firewalls may have difficulty accessing this. If that is the case, please download the [ slides] (where applicable) and running them locally. The speaker(s) will prompt you to advance the slides during the talk.     (1D7C)
  • RSVP to appreciated, ... or simply just by adding yourself to the "Expected Attendee" list below (if you are a member of the team.)     (1D9)
  • Please note that this session may be recorded, and if so, the audio archive is expected to be made available as open content, along with the proceedings of the call to our community membership and the public at-large under our prevailing open IPR policy.     (1D11)

Attendees     (1E)

  • (discussion 2011.05.06):     (1F28)
    • an adopted Architecture & API is definitely crucial, but that's not all     (1F28A)
  • All team members are encouraged to mull over how we can get to that state effectively     (1F29)
    • in particular ... how do we make this a "successful" community-driven, open source project!?     (1F29A)

    • we need a gatekeeping/policy module in place - [KenBaclawski]     (1F34A)
  • 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 ...     (1F35)
    • 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.)     (1F35A)
    • 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     (1F35B)
    • we will make to be an ontology registry, which then links to the ontologies in the actual ontology repository where the ontology is described     (1F35C)
    • 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     (1F35D)
    • after that, we will focus on building up content with each OOR node tackling the domain(s) they are best with     (1F35E)

[6:59] Peter P. Yim: Welcome to the     (1G7)

OOR "Hackathon" Session (n.02) - Tue 2013_07_16     (1G8)

  • Session Topic: The "OOR-Ontohub-Gatekeeper API - II" Hackathon     (1G9)

Proceedings     (1G14)

[7:03] anonymous morphed into Aleksandra Sojic     (1G15)

[7:02] Peter P. Yim: Till: ref.     (1G16)

[7:13] Ken Baclawski: The idlj compiler converts from IDL to Java. It is a standard tool in any Java     (1G19)

Development Kit (jdk) so if you have Java installed you should also have idlj.     (1G20)

[7:15] Ken Baclawski: The idlj compiler is handy for checking the IDL syntax. I used idlj to convert     (1G21)

an IDL to Java, and then it is relatively easy to convert to WSDL.     (1G22)

[7:09] Till Mossakowski: [action] we will set up a new github repository, only for the API     (1G23)

[7:07] Ken Baclawski: My GitHub name is "baclawski."     (1G24)

[7:15] Peter P. Yim: when this OOR-API github instance is up, please subscribe me too - my github     (1G25)

username is "yimpp"     (1G26)

[7:23] Till Mossakowski: [action-completed] new repository at     (1G27) ... both Ken and Peter are subscribed now     (1G28)

[7:11] Todd Schneider: What happened to the use of instances of the metadata ontology as the function     (1G29)

parameter?     (1G30)

[7:30] Todd Schneider: The API for 'selecting' is effectively a query mechanism, the front end to the     (1G31)

user. The other side of this is the 'retrieving' of the requested or queried data. For the front end     (1G32)

of selecting or querying for ontologies (or metadata about them) use of an instance of the metadata     (1G33)

ontology should be used as the single parameter for the 'select' method. The particular parameters     (1G34)

of interest would be represented by non-null values (in the ontology instance). This simplifies the     (1G35)

API and overall architecture (but moves complexity to the parsing of the ontology instance). The     (1G36)

retrieval (or return values) of the 'selected' results would make use of federate identifiers.     (1G37)

[7:35] Till Mossakowski: @Todd: the single parameter should be a struct     (1G38)

[7:39] Till Mossakowski: add-on to Todd's message: the user should be able to select whether the     (1G39)

method call should just deliver ids (compact representation) or all the metadata (say, as an XML     (1G40)

tree), or even the whole ontology/ies (can become very large)     (1G41)

[7:42] Todd Schneider: Till, good point about a parameter to specify return value(s).     (1G42)

[7:42] Till Mossakowski: IDL methods are synchronous by default. If the execution of a method takes     (1G43)

very long, it should be made asynchronous (keyword: oneway).     (1G44)

[7:33] Ken Baclawski: I have posted the Gatekeeper API in gatekeeper.idl. This is accepted by idlj.     (1G45)

[7:44] Peter P. Yim: Till+Ken: now online at github:     (1G46)

[7:47] Till Mossakowski: Daniel will work on a new iteration of the API, and test it with idlj. He     (1G49)

will also integrate the gatekeeper API as a module. Once this iteration is there, Daniel will send a     (1G50)

mail, and others can contribute through github.     (1G51)

[7:47] Peter P. Yim: [consensus] we will leave these two API's as separate modules - OOR-Ontohub-API and     (1G52)

OOR-Gatekeeper-API     (1G53)

[7:48] Peter P. Yim: (for the lower level development work) we should use the [oor-dev] mailing list     (1G54)

[7:48] DanielCoutoVale: my e-mail is danielvale [at]     (1G55)

[7:49] Peter P. Yim: [action] I will subscribe everyone present at today's session to the [oor-dev] list     (1G56)

(in case he/she isn't yet)     (1G57)

[7:49] Peter P. Yim: ^[action-completed] ... done subscribing everyone here onto the [oor-dev] list!     (1G60)

[8:04] Todd Schneider: Sorry; Have to go. Thank you.     (1G61)

[8:01] Till Mossakowski: we just need to start with the "upper level" of the classification.     (1G62)

People can later add finer distinctions. The classification system should be itself an OWL ontology,     (1G63)

hosted at OOR-Ontohub.     (1G64)

[7:53] Ken Baclawski: Another source of ontology classification (or perhaps properties of an     (1G65)

[7:57] Till Mossakowski: United Nations Standard Products and Services Code:     (1G67)

[8:03] Peter P. Yim: @Ken - UNSPSC codeset can be downloaded at:     (1G68)

... (generally cost $100) the pdf's are free     (1G69)

[8:06] Mike Bennett: Prescriptive v Descriptive ontologies     (1G70)

[8:07] Till Mossakowski: follow up to Ken/2007 summit: ontologies may be classified as descriptive or prescriptive     (1G71)

[8:07] Mike Bennett: (that is extensional v intensional definitions in the ontology)     (1G72)

[8:08] TillMossakowski-KenBaclawski: The Ontology Summit 2007 Communique is     (1G73)

[8:11] Peter P. Yim: upcoming meetings: OOR-hackathon n.03 - Tue Jul-30 ... break in Aug-2013     (1G75)

... OOR-hackathon n.04 - Tue Sep-10     (1G76)

[8:11] Peter P. Yim: we will use the second Tuesday of each month for the OOR-hackathon activities     (1G77)

[8:11] Peter P. Yim: same regular start-time: 7:00am PDT / 10:00am EDT / 4:00pm CEST / 3:00pm BST / 1400 UTC     (1G78)
