    • 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.)
    • 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.)

Chat Transcript

[07:17] Till Mossakowski: slides also available at http://iws.cs.uni-magdeburg.de/~mossakow/2014-07-22_Ontohub_API.pdf

[07:19] Todd Schneider: Does the generated specification depend on the coding language?

[07:28] Todd Schneider: So a query is not treated as an object?

[07:30] Todd Schneider: The description of ontologysearch is not clear to me.

[07:31] Till Mossakowski: slide 13...

[07:34] Todd Schneider: What is the context of the APIs? Instances of ontohub (i.e., inter-ontohub)? End users? Both?

[07:36] Todd Schneider: Are 'accepts', 'registers with', 'informs' API commands?

[07:37] Todd Schneider: How does 'reliance' handle end-point or communication failures?

[07:41] Till Mossakowski: Todd: does the API cover authentification? Tim: yes, using an authorization token approach.

[07:42] Mike Bennett: This might be a naive question: can these API commands be executed from the command line? So that for instance a scheduling tool like Jenkins could invoke them?

[07:45] Till Mossakowski: Tim's answer: yes.

[07:46] Mike Bennett: Can you search on ontology imports i.e. get a result showing how ontologies import from one another?

[07:46] Till Mossakowski: Todd: Does the generated specification depend on the coding language? Tim: we use ruby, and the DSL will be based on ruby.

[07:51] Till Mossakowski: Tim: in the API, ontology-related queries use the IRI of the ontology, followed by a command. Other queries consist of just the command. In both cases, there may be additional parameters.

[07:51] Till Mossakowski: Todd: why constrain this prefixing approach just to ontologies?

[07:52] Till Mossakowski: Todd: the general approach to use a IRI as a prefix that gives the context to the subsequent command is interesting.

[07:53] Till Mossakowski: Todd: the prefix approach could be used for any resource (text files, image files, ...), not just ontologies.

[07:54] Todd Schneider: Can imports be considered as a 'type' of [ontology] mapping?

[07:55] Till Mossakowski: Mike: Can you search on ontology imports i.e. get a result showing how ontologies import from one another? Tim: this would be a textual representation of the ontology graph. Would be interesting to add this.

[07:57] Todd Schneider: Would it make sense to include a 'resource type' as part of the prefix?

[07:57] Till Mossakowski: Tim: until now, we compute all query answers on the fly, later on, caching will be needed.

[07:57] Till Mossakowski: Tim: imports are a kind of ontology mapping.

[07:58] Ravi Sharma: thanks for answering search during import on the fly.

[08:00] Mike Bennett: I have to drop off now

[08:01] Till Mossakowski: Todd: Would it make sense to include a 'resource type' as part of the prefix? Tim: yes, we should think about this, to prefix or postfix the IRI with the type, in order to ensure that the command is relevant in the given context.

[08:04] Todd Schneider: Thank you.

[08:04] Till Mossakowski: Agreement: in a few weeks, have will a follow-up meeting, with discussion of more details.

[08:04] Ravi Sharma: thanks

[08:05] Till Mossakowski: Next week: general OOR strategy discussion.

[08:05] Tim Reddehase: Thank you all for the suggestions and revealing questions.
