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.
