SAMP v1.2 RFC Discussion

This page contains public discussion of the SAMP v1.2 Proposed Recommendation.

Change summary

Version 1.2 is a minor revision of the first SAMP Recommendation, v1.11. The changes are detailed in Appendix B of the document, and consist of only two items:

• Introduction of new SAMP_HUB environment variable lockfile location option documented in section 4.3. This is a backwardly-compatible modification of the existing SAMP "Standard Profile".
• Addition of Non-Technical Preamble section 1.1 as per agreement for all new/revised IVOA documents.

Neither of these items is subject to unresolved controversies within the Apps/SAMP community.

It should therefore be very easy for TCG members to examine the changes and comment on approval/disapproval!

As before, the SAMP document has been developed within the public subversion repository Volute, in directory projects/samp/doc, so especially conscientious reviewers can see the exact changes by diffing the (LaTeX) source code between the v1.11 REC and current version.

Implementations and Validators

There are two interoperating implementations of the entire SAMP standard, by different authors, in different langauges, including the new SAMP_HUB feature:

• SAMPy 1.2.0 (Python)
• JSAMP 1.1 (Java)

JSAMP also includes a validation suite which performs validation of nearly all aspects of the standard. SAMPy and JSAMP both pass these validation tests.
