CRMdig update

CRMdig is highly relevant for work undertaken in many projects, but has been idle for far too long and needs to be updated. 

Topics that can be elaborated in the model: 
- Harmonization with CRMinf, CRMsci, PROV-O, Parthenos Entities Model
- Digitization (see how the human activity relates to the reaction of the machine: for the moment, the human activity that sets in motion the machine reaction and the machine reaction itself are inseparable. What is the temporal and other connection between these two events? Can they be seen as one and the same event?)
- Formal Derivation (Metadata descriptions for digital objects carry over from original to derivatives -assuming the latter retain features of the original digital object.)
- Unreliable transfer 
- The relation among D9 Data Object and E54 Dimension and PE22 Dataset (D9 IsA E54 AND D9 IsA PE22)
- The relation between D3 Formal Derivation and S6 Data Evaluation
- D7 Digital Machine Event as E7 Activity vs. triggering an activity.
- F54 Utilized Information Carrier

Decision of the 50th SIG: to pursue this line of work further. Form a working group, formally raise a number of issues through the SIG mailing list and take it from there. 

WG: CEO, SdS, GH, ML

Documents to consider: 

(1) About CRMdig, (2) PEM, (3) Repository for 3D Model Production and Interpretation in Culture and Beyond, (4) 3d_metadata, (5) CRMdig_v3.1, (6) CRM digital (2.3)

HW: the WG to draft a number of issues for CRMdig.
 

In the 53rd CIDOC CRM & 46th FRBRoo SIG meeting, the SIG decided to continue in this line of work. 

Proposal: 

• Look at CRMdig, determine what parts of the model need to be kept in CRMdig vs the things that echo the project they were built to describe.
• Discuss the overlap with PEM. 
• Break the model in small subtasks (review properties, Digital Objects etc)

HW: GB to coordinate the group of people involved in this task, CEO, (MD), and confer with ML and GH. Inform the Sig in the next meeting.

Dear all,

Given that CRMbase 7.1.1 is now a static entity and needs to be so for the purposes of shepherding it through the ISO process (shout out to Philippe and Erin!), now seems a good time to be doing some consolidation on the many extensions and trying to tighten up official versions of these.

I have taken up the mission of consolidating notes and thoughts from the past few years regarding CRMdig and how to bring it into line with the best practices we have evolved at the CRM SIG. 

I have, as a result, formulated the following three powerpoints / proposals:

• CRMdig Cleanup: https://docs.google.com/presentation/d/1xg9PvWh3BPmP_mcnEK5HmbPlj4NvH_MB_Z_7VT7J0uc/edit?usp=sharing 
  In which I propose a number of deletions and general consolidations to make the extension accord with 7.1.1 and its practices. Here I should acknowledge Rob Sanderson and Nicola Carboni for work which we did on this a number of years ago which I have borrowed from (hold them not responsible for any apostasies!).
• CRMdig and CRMpe (Parthenos Entities): https://docs.google.com/presentation/d/1yqqnfEtoM2TJYvliwSVgbYmJoDBXbzh8KUHL7Saa-0M/edit#slide=id.p 
  Some time ago (it was in Paris in 2018 I think) we agreed to look into how to integrate the work of the Parthenos Project that was relevant to CRMdig into a common framework. In this powerpoint, I illustrate the basic proposals of CRMpe and make some proposals as to what elements might become parts of CRMdig (and other models).
• CRMdig and CRMsoc: https://docs.google.com/presentation/d/1Wh3Vb9LInY7w_zx33ixwBvPboI7IxrKPyP5VOyMabik/edit?usp=sharing 
  In looking over CRMdig, the annotation modelling particular stood out as an outlier and not properly a question of digital workflow. I've done extensive work on how to cover this using the structures of CRMsoc, so here I put in an illustration of how that could be coherently harmonized.

The key point of this exercise, to my opinion, should be to focus on a cleanup of CRMdig that brings it into coherence with our present practice at CRM SIG but also takes into account the knowledge and experience of people who have used it and who have knowledge of other standards and well known practices in the community that should be taken into account.

Therefore, I present the above as a working framework for a discussion and to announce that we will start to have the discussion of improving CRMdig.

For those of you who are interested in the topic and have opinions on what is done right or wrong there, it would be great to hear your input, nothing suggested above is set in stone, but is meant to start the conversation.

To that end, if people want to make structured remarks regarding the proposals before the meeting, you can of course always use the emailing back and forth feature of the list OR you could make your remarks in this handy google doc I have constructed for that purpose:  https://docs.google.com/document/d/1Qn9I3wsZYJIJ0NoHkzyolCLPX1YvdHv8-48TtiOkk8o/edit?usp=sharing

This review is well overdue and is a nice, concentrated piece of action which we could take up to facilitate the CRM community's modelling work, so I do look forward to constructive and pragmatic discussions!

Best,

George

In the 54th CIDOC CRM & 47th FRBR/LRMoo SIG meeting, George Bruseker shared a proposal on redefining constructs of the model. Details can be found in the CRMdig Cleanup document. 

Decision: SIG members back the proposal by George. Stephen Stead wants to collaborate (to test with examples from work he’s currently undertaking with a group in San Francisco), Martin Doerr and Thanasis Velios have volunteered to work on the harmonisation of CRMdig and PEM.
