      Description

      An early draft of a proposal is being circulated in the IVOA Data Access (DAL) working group for a service that would return the parameters of scheduled observations from a facility.

      This may be relevant to our meeting requirement DMS-REQ-0353 which calls for us to publish our observation schedule two hours in advance.  The proposed protocol would be an ObsTAP-like "pull" service; we might also wish to contemplate a "push" service similar to VOEvent, and we might wish to discuss with our colleagues whether a common data model could be used for the two.

      The work in this ticket, at first, would be to review the draft proposal, discuss its substance with other relevant LSST team members, and then communicate back to the proposal's current authors.  We could decide on any action ranging from ignoring it, making an alternate proposal independently, or even becoming co-proposers.

      for a presentation on this from the May 2018 IVOA meeting.  Of the two complementary services proposed, "OLAP" is the one relevant to meeting the  DMS-REQ-0353 requirement.  We could also implement the simpler OVAP, but it is basically scheduler-independent and is only aimed at reporting what an observatory could see on the sky if it chose to.
