Issue 373: Managing CRM and CRM extension versions

Starting Date: 

Posted by Thanasis Velios on 9/5/2018

During the last meeting we agreed to review the way that the
documentation about CRM base and its extensions is managed. This is
probably as part of issue 358, but there have been messages in the list
about this issue (e.g. by Rob, but I can't find the reference)

Francesco, George and I discussed this and produced the following text,
which is a first attempt to specify what it is we need:


# Specification of CRM-SIG work

## Functions

### Versioning:

* manage CRM core and extensions document versions, i.e. specifying the
classes and properties (and their versions) which exist in each
document, to ensure coherence among versions of extensions and CRM core
* manage content changes in the class and property declarations in
current document version (including scope notes),
* document arguments for each committed change and dismissed proposal

### Visualization:

* visualize class and property hierarchies
* visualize combinations of extensions with CRM core
* visualize evolution in time of CRM core and extensions

### Serialization:

* produce a formatted encoding (e.g. PDF file) for each document version
* produce an RDFS encoding for each document version

### Interpretation and best practice:

* capture discussions about classes, properties and their meaning
* recommend best practice at implementation level

## Roles

* SIG members: participate in meetings to make decisions on version and
scope note changes
* version maintainers (SIG): collect contributions, editorial work,
animate and moderate the discussion in the community, ensure completeness
* version contributors (SIG) : produce and discuss the content
(including serializations) and propose changes
* public (non-SIG) : discuss the content, raise questions on interpretation

### Access level

* Public, contributors and SIG members raise questions, discuss
proposals, comment, answer questions
* Contributors can create issues and recommend changes at any level
* Maintainers summarize/introduce issues for discussion in the SIG
* SIG members 'vote' on issues, classes definitions, ...

## Existing platforms:

* Drupal in FORTH (existing but not accessible for contributors and
* application (open, but still under development) +
an internal forum / API
* GitHub (versioning, discussions, API)


It would be useful to receive feedback on whether this captures the
SIG's activities and whether there are any other platforms we should be
considering. We can then assign people to evaluate the different
platforms, so volunteers with expertise on a platform are welcome. 

Current Proposal: 

In the 41st joined meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9 and the 34th FRBR - CIDOC CRM Harmonization meeting, the sig decided to ask George, Oyvind and Francesco to collaborate for making a proposal about improving the design of CIDOC-CRM site and making implementations' proposals.
