Create an Archive with the Thredds Data Repository (TDR)
The main focus of the TDS has been to serve near real time data that arrives at a server
by a scheduled delivery system such as our Unidata Internet Data Distribution
(IDD) network.
As a complement to this focus, the THREDDS Data Repository (TDR)
provides client initiated, on demand storage for data to be served by
the TDS. The TDR provides functionality to:
- store data files and create catalogs
- manage storage space on the server
- upload files via HTTP (and support for gridftp)
- upload a collection of data as single file
- maintain support of repository contents via add, remove, move, copy of datasets
- incorporate metadata provided by the client
- generate additional metadata
- edit metadata
To date TDR development has been steered by two use cases:
- the LEAD project
- goal: to provide a publicly accessible repository for published information
- callable via a programmatic client
- the Next Generation Case Study (NGCS) project
- goal: to provide a publicly accessible case study repository
- maintained over time by humans
TOUR
Structure
- Separate webapp,
tdr.war, though integrated with the TDS
- Like TDS, intended to be deployed and maintained by community sites
- One TDR server can have multiple
partitions
, e.g. ngcs
and lead
- separate data and catalog spaces
- separate interfaces: ngcs interface communicates with a browser
Future Plans and Ideas
- Scale up
- User interface improvement
- Explore storage options: remote storage, mass storage
