Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

This looks like a good attempt to handling the issue of multiple access interfaces for the same dataset and it seems fairly straightforward to me. One comment, I don't think OpenGIS is a service type. Rather specific OpenGIS services would be individual service types - such as WMS, WCS, WFS, etc. The service type specification implies the resulting output of the service and how to communicate with it. In the same sense that specifying type=DODS lets a DODS client know that it can then get data from the described server, then type=WCS would let a WCS client know that the server is compatible. -----Original Message----- Sent: Tuesday, May 14, 2002 1:28 PM Proposed changes to the THREDDS catalog format are at: http://www.unidata.ucar.edu/projects/THREDDS/tech/InvCatalog6.html The current format is documented at: http://www.unidata.ucar.edu/projects/THREDDS/tech/InvCatalog5.html Summary of changes: a.. add <attribute> elements to collection, dataset, service b.. rename "server" element to "service". c.. add new service types: (DODS | ADDE | NetCDF | Catalog | FTP | OpenGIS | WSDL | Other) . d.. allow multiple services per dataset: add <access> child element of dataset, where you list any number of services for that dataset, and add <serviceList> element so you can define a list of services. "serviceId" now refers to either a service or a serviceList. Use a serviceList when the same dataset urlPath can be appended onto all service bases. e.. generalize <datasetDescRef> element to <metadataRef>, where "DatasetDesc" is one of several metadata types. proposed types: (DatasetDesc | DublinCore | DIF | ADN | FGDC | LAS | Other) f.. add "ID" and "alias" attributes to dataset, so that a dataset can be an alias to another dataset. Please send comments to me or to this list.
