This site contains information about the PDS4 prototype migration effort to be conducted at the Small Bodies Node in the Fall of 2012/Winter of 2013. It will eventually contain both tracking information and potentially useful support information for PDS4 data developers inside and outside the SBN.


Discipline and Mission Dictionaries

Here are some quick links to the latest versions of the local dictionaries in development here:

  • SBN Discipline Dictionary (no Schematron file) - This contains classes and attributes useful across all SBN data sets, including ground-based coordinates and general observing parameters.
  • SBN Geometry Dictionary (no Schematron file) - This is a placeholder for a broader geometry dictionary. It contains mainly classes for distances, position vectors, and velocity vectors.
  • Ground-based Geometry Dictionary (no Schematron file) - This is a placeholder for a broader geometry dictionary specifically for ground-based observations. It's not clear whether ground-based geometry will be included in the geometry discipline dictionary that will be developed by PDS, so this was generated as a separate entity, just in case.
  • IUE Mission Dictionary (no Schematron file) - This is a draft of the IUE mission dictionary. It has the stuff that the XML editor needs for validation, but does not contain any human-readable definitions.
  • Deep Impact/EPOXI Mission Dictionary (no Schematron file) - This is a draft of the DI/EPOXI combined mission dictionary. It contains human-readable definitions as well as most of the stuff needed for validation. There are a few standard values lists still outstanding. If you would prefer to see attributes organized differently, give me details.

If you're looking for older versions, you can check the corresponding folders in the http://pdssbn.astro.umd.edu/PDS4test/WikiSupport/Dictionaries/ directory.

Mechanics

How to do things - questions and answers:

  • How-To - Quick tutorials on specific tasks or problems, including things like setting up editors and running validators, or understanding what you're typing into the PDS4 labels.
  • Questions - If you have questions about the mechanics of creating labels, using the XML tools, what you can and can't do in terms of structure, etc., this is the place. We'll try to answer them ASAP.
  • Templates - Here I'll post commented XML templates of SBN label archetypes. You can use these as starting points for making new labels, rather than starting from scratch and the PDS master schema.
Note: The mauve-y boxes indicate significant problems that need to be addressed for Build 3b (the post-migration test build). You may assume I will file RFAs on these, so you don't need to take any additional action on these unless specifically requested by the note. Thanks!

References

Here are some intros and background material for those new to the process:


  • XML Primer for PDS4 - If you have no idea what any of this XML stuff is about, read this page for some basic context and terminology.
  • Understanding XML Catalog Files - XML Catalog files have nothing to do with archiving or PDS3 catalog files. Rather, they provide a method for referencing schemas that makes life easier for those working on large or multiple projects, who like to keep their workspace nicely divided and organized.


And here is local documentation:

  • SBN Discipline Dictionary Page - This is where we'll gather the information we'll need to create a small bodies discipline dictionary, as well as the mock-ups I'll put together by hand until there is a real data dictionary tool. (You'll need the mock-ups for validation work.)
  • Repository - This will take you to the Repository that we're actively building so you can access the files that have already been migrated (when there are some), as well as older repository versions for comparison. Note that this area will always be under construction! Things will change - see the AAREADME file for details. If you encounter unexpected problems with the files in here, please post them so we can fix/explain them. Thanks!
  • Standard Values Quick Reference - A compilation of the standard values used for common attributes in the core classes, with notes of particular relevance to SBN data preparers. The attributes are listed alphabetically, and standard value lists for different contexts (containing classes, that is) are listed under those, where applicable. The list doesn't include meanings for the values, largely because they are not yet available - publicly or privately.

Accounting

Here's where we'll keep track of the various projects in progress at the node sites.

  • Tracking - The data sets to be migrated for this first major prototype migration, showing any progress and with notes on specific issues and problems encountered.
