IVOA RFC for Space Time Coordinates document

[Jonathan McDowell]

Dear IVOA,

 Since there have been no objections to the version of Space-Time Coordinates
(STC) posted as Proposed Recommendation on Mar 18, I call for the
formal Request for Comments on this document.
    http://www.ivoa.net/Documents/latest/STC.html
The RFC is at
    http://www.ivoa.net/twiki/bin/view/IVOA/STCMetadataRFC


 - Jonathan McDowell, DM Working Group.

 

>From the IVOA documentation doc: 
: Next maturity level.  After a publication period of at least two weeks,
: the chair of the Working Group that developed the Proposed
: Recommendation may call for a formal Request for Comments (RFC).  The
: RFC is sent to the widest possible IVOA distribution lists
: (interop at ivoa.net) and announced on the website.  Distribution of the
: RFC initiates a four-week public review period.  All comments submitted
: during this review period must be posted publically (SIC) and responded to
: publicly.  If the review identifies significant deficiencies in the
: document, such that revisions must be undertaken beyond minor editorial
: changes or where revisions require changes to software based on the
: document, the document must be returned to the Working Draft status.
