As you know we’ve been advocating a move from flat files to XML for GPS metadata for many years. Working with you on the NASA GSAC project, we updated the XML schema to include metadata about real-time GPS stations, and the extra information content is what distinguishes it from traditional log files. I’ll check with Mindy if our documentation on the web site is up to date.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>So we’re </span><b>planning to participate in discussions and work on implementation.<o:p></o:p></b></p><p class=MsoNormal>Best Regards,<o:p></o:p></p><p class=MsoNormal>--Yehuda<o:p></o:p></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='margin-bottom:0in;margin-bottom:.0001pt;line-height:normal'><b><span style='color:windowtext'>From:</span></b><span style='color:windowtext'> Fran Boler [mailto:boler@unavco.org] <br><b>Sent:</b> Friday, January 9, 2015 9:01 AM<br><b>To:</b> IGS-DCWG@igscb.jpl.nasa.gov<br><b>Cc:</b> Yehuda Bock; msquibb@ucsd.edu; David Maggert; Gary Johnston; Gary Mize; Nacho Romero; artur.oruba@gugik.gov.pl; bradke@gfz-potsdam.de; mark.caissy@nrcan-rncan.gc.ca; Chuck Meertens<br><b>Subject:</b> Invitation to participate - IGS metadata exchange via XML<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:12.0pt;line-height:normal'>Author: Fran Boler, Carey Noll<br><br><br>Dear Colleagues-<br><br>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 rapid updating 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 (<a href="http://sopac.ucsd.edu/xmlGeodesy.shtml">http://sopac.ucsd.edu/xmlGeodesy.shtml</a>), and this is the ideal starting point. We would like to kickoff this effort by requesting feedback on the SOPAC Site Log XML schema. <br><br>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. <b>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”. </b>(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.)<br><br>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.<br><br>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 <a href="http://igscb.jpl.nasa.gov/mailman/listinfo/igs-dcwg">http://igscb.jpl.nasa.gov/mailman/listinfo/igs-dcwg</a>.<br><br>Kind regards,<br>Fran Boler, IGS Governing Board Data Center Representative<br>Carey Noll, IGS Data Center Working Group Chair<br><br><span style='font-size:12.0pt;font-family:"Times New Roman",serif'><o:p></o:p></span></p></div></body></html>
