Dear Thomas,
By using GI-cat, you may extend any THREDDS data server by publishing
one or more of the following discovery interfaces:
(a) CSW core (i.e. Dublin Core)
(b) CSW/ISO/ebRIM profile;
(c) OpenSearch with GEO and Semantic extensions
(d) OAI-PMH
GI-cat makes use of the ncISO service developed by NOAA.
Hope that could help.
Best regards,
Stefano
Dear all,
In myOcean poject, we are looking for a "light discovery interface" on
our data servers (THREDDS Data Server being the main software used
for data dissemination).
I am wondering if providing opensearch interface on THREDDS catalogs
is something which may be considered in future releases of THREDDS
Data Server.
I have seen different documentations about software which provide
opensearch interface with THREDDS catalogue inputs :
GI-CAT :
http://essi-lab.eu/cgi-bin/twiki/view/GIcat/THREDDSGuide
A slide show about THREDDS+opensearch :
http://vimeo.com/30452893
An opensearch interface directly provided by THREDDS Data Server would
prevent data providers from installing and maintaining additional
software.
Besides THREDDS provides metadata/search protocols which we could use :
http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.2/reference/ncISO.html
But the iso19115 is not the kind of metadata service we are searching
for.
An OGC/CSW with Dubin-core metadata may also be an interesting
alternative to opensearch.
Have you any update plans for this ncISO services ?
We might also use the THREDDS XML but an overall search interface on
which criteria could be applied could be interesting.
Thanks very much,
Thomas
