Mirroring the IRI Data Library using DODS and THREDDS
March 2003
We have set up a mirror of the IRI Data Library using DODS/OpenDAP and
THREDDS to transfer the data, metadata, and collection structure
between the two sites. We are using standard HTTP software to cache
the metadata, and custom code to incrementally cache the data on the
mirror site. Once the code is more fully developed, a similar
system should be able to cache from the entire collection of THREDDS
servers.
A mirroring scheme has three key parts: a server, a client, and a
cache.
| Server
| - | serves datasets using THREDDS and DODS
|
|---|
| Client
| - | views, manipulates, and re-serves a THREDDS/DODS dataset collection
|
|---|
| Cache
| - | maintains a local copy of the information
|
|---|
| Suggestions
| - | Our experience leads to some suggestions for both the THREDDS and
DODS/OpenDAP standards.
