AMD Portal Update: Still Beta? http://gcmd.gsfc.nasa.gov/KeywordSearch/Home.do?Portal=amd-beta&MetadataType=0
AMD Portal Update: Next Steps - Beta site is still running parallel to existing AMD site. - Any outstanding issues with new site that need to be addressed? - If all issues are resolved, we can schedule replacement of existing site with updated site.
Different Methods for Metadata Submissions • docBUILDER (one DIF at a time) • FTP site (metadata records made available via secure site for GCMD to access)* • Harvest via OAI-PMH (metadata records made available to GCMD to access via harvesting protocol)* • Bulk Uploader (validate and/or submit multiple metadata records in DIF format directly to GCMD)* • ISO records (metadata records in ISO format may be submitted via FTP site or OAI-PMH harvest; GCMD will translate to DIF format)* *Contact Alicia Aleman email@example.com
Submitting DIFs via Harvesting Protocol (OAI-PMH) • Send the following information via email to: firstname.lastname@example.org • Repository name • Repository base URL (i.e. http://mercury.ornl.gov/oai/provider) • Metadata format being harvested (i.e. oai_dif) • # DIFs • Frequency of harvests
Submitting DIFs via Bulk Uploader Online Interface • Upload multiple DIF records to the GCMD metadata queue • Validate records (links and syntax) and send an email to the provider with validation results • NASA EOSDIS/URS authentication required for access: • https://urs.eosdis.nasa.gov/ AMD data providers who want to use the new tool should send an email to email@example.com
Very Important! When authoring DIF records outside of the GCMD/AMD (docBUILDER), please make sure to use the current DIF schema and Keyword sets. XML DIF Schema: http://gcmd.nasa.gov/add/difguide/index.html Download Keywords (CSV): http://gcmd.nasa.gov/learn/keywords.html Access Keywords via KMS (RESTFul; SKOS, RDF or OWL ): http://gcmd.gsfc.nasa.gov/Connect/
GCMD Software Updates (May 2014) • MWS new default behavior: A fix to the Metadata Web System RESTFul API was implemented to return XML as the default format instead of plain text for a query’s output. • New Portals: Southern Ocean Observing System (SOOS); Swedish Antarctic Research Program • Delete flag added to md_entry and service_entry. This new feature allows DIF and SERF metadata records that have been deleted to be automatically ‘flagged’ and found via the Metadata Web Service (MWS) using the following query syntax: /mws/dif/<entry_id>?deleted=true or any query with 'deleted=true'. http://gcmd.nasa.gov/learn/release_announcement.html
