Notes on HIS Data Services Center
¶
What is Hydrologic Metadata
¶
Observations metadata (observations catalogs)
References to spatial data sources
References to web services related to hydrologic data
Storage of composite objects
Ontologies and controlled vocabularies
Functionality
¶
Registration, upload, crawling
Registration of services (a preliminary description is at the
Central HIS pages
)
Upload of ODM, and virtual servers for ODMs
Eventually: upload of netCDFs, an THREDDS servers
Harvesting catalogs from registered services
Syncing with catalogs in HIS Servers
Data discovery system
Global search (Hydroseek)
Finding data, and passing discovery requests to lower-level HIS servers
Analysis of data availability with data cubes (data cubes constructed for federal agencies, and for watersheds on demnand)
Maintenance and updates
Periodic updates of agency catalogs
Ontology management
Controlled vocabulary management system
Tagging of variables with ontology
Management of GUIDs
Maintaining framework datasets
Provenance management
Virtual servers for submitted ODMs and gridded data
Monitoring of hydrology data resources (e.g. "hot page"/"hot map" for registered HIS servers)
Interoperability
Standards support
Standards for data discovery
Interfaces to other metadata stores, in other disciplines (wrapping search services of other portals)
Search across portals
Research on interoperability across hydrologic and related datasets; eventually support for ETL tools
Export
Export in different metadata formats
Maintaining extract services
Conversion services
Long-term preservation of catalogs and framework data
A synopsis of long term preservation issues for observational data, from Nov 2007
Usage reporting
Maintaining logs, reports on demand and periodically
Support for metadata center users
