PDS3 to PDS4 Migration Workshop

This page contains needed prior to the introductory label-writing workshop held 2012-09-04 at UMCP. The workshop lasted 2 hours.

Workshop Goals

1. Giving the participants a chance to work with a validating, schema-aware XML editor (in this case, eclipse);
2. Developing a broad, general sense of where the complexities are in migrating PDS3 labels (largely in the meta-data, rather than the data structures); and what things need to be addressed before migration of any particular data set (or data sets generally) can begin.
3. Providing a superficial introduction to the PDS core document set, in particular the master XSD schema and the Data Dictionary document, as reference documents

Pre-workshop Downloads

Here's a link to a zipped package containing all the downloadable files listed below:

Here are individual links to various bits and pieces needed for creating PDS4-like versions of the PDS3 sample labels:

• Data Dictionary Mock-ups - These XML Schema files can be used to try out validation across multiple namespaces:
  • SBN Discipline Dictionary Mock-Up (use Save As to download the file)
  • Imaging Discipline Dictionary Mock-Up (use Save As to download the file)
• PDS Schema Files - these appear to be the latest versions available:
  • PDS4_PDS_0910B.xsd - XML Schema, used for validation (use Save As to download the file)
  • PDS4_PDS_0910B.sch - Schematron, used for validation (use Save As to download the file)
  • PDS4 Data Dictionary - a PDF file that you'll probably want to keep open for searching while you're editing to look up attribute definitions
• Other PDS4 Documentation maintained at PDS/EN

Here's the data set we'll be using as our source:

• ear-c-i0039-2-sbn0007_keckiiesi-v1.0

We'll start with this table label:

• data/wild2astrom.lbl

And, time permitting, move on to this image label:

• data/2003dec19/processed/esi0012.lbl

You'll probably also want to reference these catalog files:

• catalog/dataset.cat
• catalog/obs378t2.cat
• catalog/i0039.cat

Post-workshop Results

We worked through the first sample label (the ASCII table label) to the point of beginning the process of documenting the individual columns. Some of the details in the Observation_Area class were ellided, and the Discipline_Area was covered very quickly, mainly with reference to what is going to be needed to create a discipline dictionary.

The label for the ASCII table will be completed shortly and posted to this page for downloading.
