[seek-dev] RE: registry metadata and design

[Bing Zhu]

Matt,

I read your wiki page, our design docs in Seattle and the current
implementation
of registry. The design doc looks good.

Here are my comments regarding implementation of Ecogrid registry service.

1. registry interface
       Here is a list of operations in current registry interface.
          RegEntry getEntry(String serviceName)
          int registerEntry(String serviceName, String serviceRegName,
String serviceWebAdd)
          int updateEntry(String serviceName, String serviceRegName, String
serviceWebadd)
          int removeEntry(String serviceName)
          RegEntry getEntryByRegName(String serviceRegName)
          String getXMLListing(void)
          String getXMLEntryByName(String serviceName)
          String getXMLEntryByRegName(String serviceRegName)

      And I took a look of the implementation, compiled the code and they
looked fine. Basically we just need
      some modifications based on these operations especially for remove(),
update() and registerEntry() after
      we decided to have a new authentication service. I will modify the
gwsdl tomorrow. And if you have any
      comments, please send them to me asap.

2. Store registry entries in Metacat.
       We can create a user account which is dedicated for registry only,
say 'EcoRegAdmin'. we store all registry
       entries using this Metacat user account. In this way we avoid avoid a
problem of having a 'collection' just
       for registries. i.e. in querying all registries in Ecogrid, we just
need to search all documents owned by
       user 'EcoRegAdmin'.

Sincerely,
Bing

Bing,

Here's the thoughts I said I would send your way regarding registry
metadata and the design and implementation of the registry.  Instead of
putting it in an email, I created a wiki page so that you and others
could add to it and revise it in a coherent way:

http://seek.ecoinformatics.org/Wiki.jsp?page=EcoGridRegistryDesign

It covers registry metadata, implementation, service identifiers,
distributed regitries, and links to earlier notes, documents, diagrams,
and prototypes.

It's just a first pass, so please feel free to revise it and add to it.
  It would be good if all the EcoGrid contributors reviewed this as it
progresses.

Matt
