      Description

      03/12/2019 CADC TAP service was added to the list of Firefly TAP services.

      http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/tap/ is often unresponsive, when called from IPAC. CADC #75724 was created for this issue with the following response from Patrick Dowler at CADC:

       

      We have been able to reproduce this and it seems to be a strange network issue... could be some network security equipment near our end. We did also discover that https seems to resolve it and we have recently converted all our web services to use https only (in the capabilities docs - not yet propagated in IVOA registries)

      I don't think we will be able to solve this for http but https appears to work so I will close the ticket. Thanks again for bringing it to our attention - I found evidence in logs that it also effected other services as well.

       

      Firefly is now using 

      https://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/tap end point.

      Please add the CADC TAP service at http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/tap/ as soon as reasonably possible to the standard list of TAP services in the Firefly TAP search screen. This is a very useful service for testing, both because of content and because it's based on the same code that Christine Banek is using for the LSST TAP service.

      This service has both ObsTAP (ObsCore format, table ivoa.ObsCore) and CAOM2 image metadata collections, which are a valuable resource for our development.

      At this moment, something goes wrong when trying to manually access this service. The message

      Failed to get schemas for http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/tap/: Error: Error from Server for command tableSearch: code: 504, text:

      appears. However, I can verify manually and/or with TOPCAT or http://saada.unistra.fr/taphandle?url=http%3A//www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/tap/ that the TAP_SCHEMA.schemas table is available.
