Thanks Craig!
If I read correctly, they want to approach the topic with MDA, PIMs and PSMs. That is interesting, I familiarized with that more than 20 years ago. But never saw it in action, so I wonder?

If we look at the argumentation of OMG, CDDS is on the right track and has a good underlying motivation. I like this one for SLE:

Subject: [CSS-CLOUD] OMG Ground Data Delivery Interface

Dear all,

The blurb below at the OMG Space Domain Task Force<https://www.omg.org/space/> website reads as if OMG also is pursuing work similar to CDDS?.  There is a 37-page PDF available at the link below describing their request.  Thought I would bring it to your attention in case you were not aware of it:

Ground Data Delivery Interface (GDDI) RFP<https://www.omg.org/cgi-bin/doc.cgi?space/2023-3-1>: Space vehicle operations require varying compositions of ground applications that are integrated together within a common network (WAN and/or LAN) to provide an end-to-end ground system capability. This includes real time data and metadata transfer across these applications. Typical data includes spacecraft bus commands, telemetry, and mission payload in digital/baseband form. Metadata is carried in-band with the data and includes parameterized information and real-time status used by the ground applications to properly process, store, retrieve, and deliver the data. No common model for this dynamic data/metadata interface currently exists. Approaches, designs, and custom protocols vary widely from one vendor to another offering little opportunity for reuse to system integrators. The result is often a costly and time-consuming integration effort. This RFP solicits proposals for the following: 1) A Platform-Independent Model describing a lightweight application-level message interface that encapsulates spacecraft data and metadata so they can be transferred between ground applications within a common network. 2) At least one Platform-Specific Model describing the encoding format of the metadata and data encapsulated by this interface. This platform specific model will call out at least one standard transport layer for carrying the encapsulated/encoded metadata and data, with the intent of reusing an existing transport that provides high throughput, low latency, and optionally secure transmission.

I don?t have any further information about OMG?s activity; just stumbled across it today.

Best regards,



Craig

Dear CDDS Colleagues,
In preparation of our next teleconference on December 10th, the CDDS Concept Book and Blue Book have been updated and are now available for your review. The CDDS messages have been aligned while the BB has been updated, it was quite useful to define the CDDS Service Models in the regard.

Please find a summary for the two books below. When commenting, please use the version on CWE (no copies please).

Concept Book: 1020x0g0-draft-1.docx<https://spacecomm.sharepoint.com/:w:/r/sites/CSS/Shared%20Documents/CSS-CLOUD/Draft%20Documents/ConceptBook/1020x0g0-draft-1.docx?d=w56054eaca69d4a668ccbef56e8c13d82&csf=1&web=1&e=jsADWV>
Changes:

  *
Security chapter updated by Erik
  *
Some alignment with BB for files

Outstanding:

  *
WG review

Blue Book: 1021x0b0-draft-1.docx<https://spacecomm.sharepoint.com/:w:/r/sites/CSS/Shared%20Documents/CSS-CLOUD/Draft%20Documents/BlueBook/1021x0b0-draft-1.docx?d=w2b7b404bdfa845159e3213b537dfb3d3&csf=1&web=1&e=zPMSuR>
Changes:

  *
A first cut on the introduction
  *
CDDS Service Models added. New: The 'service endpoints' have replaced the ?data selection'
  *
File Format Definition chapter added

Outstanding

  *
Your review and most likely quite some changes
  *
Managed Parameters for the CDDS Service Models
     *
Functional Resources following the Managed Parameters - TBC
  *
Discussion: Do we need a file service? Maybe not?
  *
Some documentation of CDDS Protobuf Types
  *
Conclusion of file metadata vs metadata in file name
  *
Annexes like PICS / ICS, Security Considerations

??????

CDDS Messages at GitHub are now a public repository: https://github.com/CCSDS-CDDS/cdds.messages
