[IGS-DCWG-84] Invitation to participate - IGS metadata exchange via XML

[Fran Boler]

Author: Fran Boler, Carey Noll


Dear Colleagues-

As many of you know, at the IGS workshop in Pasadena this past June 
there was discussion in the infrastructure and data center breakouts 
about transmitting IGS site log metadata between data centers using XML, 
using automated machine-to-machine transfer mechanisms. With the 
introduction of the IGS Site Log Manager system, we believe the time is 
right to do this. Advantages could include more rapidupdating of site 
log information, more consistent information across data centers, and 
more accurate metadata overall. Several data centers are committed to 
moving forward on this effort in the next few months. In order to 
implement such an exchange the first step will be to agree on the XML 
schema to be used. SOPAC has had a longstanding geodesy XML project 
(http://sopac.ucsd.edu/xmlGeodesy.shtml), and this is the ideal starting 
point. We would like to kickoff this effort by requesting feedback on 
the SOPAC Site Log XML schema.

Those who would like to participate in this effort should respond with 
an email (to IGS-DCWG at igscb.jpl.nasa.gov) as soon as possible 
indicating your interest. *Please mention your level of involvement as: 
“observer” or “planning to participate in the discussions” or “planning 
to participate in discussions and work on implementation”. *(Note:If 
you, as an igs-dcwg list member, do not have an interest in this topic, 
you may wish to change your subscriber option to digest for this list, 
or otherwise amend your subscription as there will be additional traffic 
during this effort.)

For those who will be active at this phase, please look at the SOPAC 
Site Log XML schema and plan to provide comments to this list within one 
month. Your comments should include any suggested amendments or 
additions. As a rough timeline we would like to complete discussions of 
the schema during February and begin discussing implementation specifics 
no later than March.

We wish to be inclusive and therefore ask you to circulate this 
invitation to interested colleagues. All interested persons should 
ensure that they are members of the igs-dcwg maillist by visiting 
http://igscb.jpl.nasa.gov/mailman/listinfo/igs-dcwg.

Kind regards,
Fran Boler, IGS Governing Board Data Center Representative
Carey Noll, IGS Data Center Working Group Chair
