[DDI-SRG] [MRT] DDI-CDI Model

Sun Feb 16 17:16:06 EST 2020

There is now a Google Drive folder with

·         The Word document with updated diagrams,

·         emf files of each diagram,

·         and an EAP of the frozen model with diagrams in  DDICDI/DDICDIModelManagement/Sandbox/LH

The diagrams for the document no longer have multiple colors for classes. Some of the original colors indicated “new” or “proposed” classes and are no longer relevant. I set all colors to the default except for a  highlighted class or two which were the focus of the diagram.
Some of the diagrams are renamed duplicates of diagrams in the model (e.g. Wide is copied to WideStructure). This was to allow for the change in colors without changing the original diagrams.

Some of the original diagrams in the document contained classes that have been deprecated or made unimportant. The LogicalRecord related diagrams are an example.

I did not have time to do much editing of text.

There are two diagrams at the end of the document referencing RAIRD and streams that appear to have come from an eap file with classes not in the model (e.g. RAIRD Key). I don’t recall where those came from (Flavio?, Jay?)

Jay:

Please be aware that Larry is updating diagrams in the Data Description portion of the model this weekend, so any changes you make will have to be merged with what he is doing, a thing which I cannot accomplish. Could you wait to look at what he has done. I will check with him tomorrow and see where he is with this. I am not sure how much he could get done without a frozen model, although I know he was looking at this.

Cheers,

Arofan

Achim:

I suggest you don’t change any of the string types. At this point that would invalidate ALL the examples I developed in a big way and perhaps ones that Larry and others have developed too.

Mostly the new model and XSD you produced from it passes regression testing. There is, however, one problem introduced when we moved InformationObject from the Process package to the DataDescription package. As a result one of my examples now won’t validate against the XSD. I have a workaround in the event the model remains frozen. Alternatively, I can test a possible fix on my copy of the current model and you can apply it if the model becomes unfrozen.

Because of this change in the location of InformationObject and because of a number of changes I introduced into the process model, it would be good to update two or three diagrams across Process and DataDescription. I can update the diagrams on my copy of the current model as you suggest below. Is that OK?

Finally, because the DDI-CDI namespace was changed, a bunch of the headers in the example XMLs needed to be changed too. Do we consider the namespace to be settled now? It is:

<DDI xmlns="http://ddialliance.org/Specification/DDI-CDI/XSD/<https://nam10.safelinks.protection.outlook.com/?url=http%3A%2F%2Fddialliance.org%2FSpecification%2FDDI-CDI%2FXSD%2F&data=02%7C01%7Clarryhoyle%40ku.edu%7Cf4f7c0cbbf784d1613af08d7b2f5501b%7C3c176536afe643f5b96636feabbe3c1a%7C0%7C0%7C637174638992303749&sdata=h1KAw7AosBTqNpcjRKD89Z6pVxbuMMSZcfNBXdtsG%2F8%3D&reserved=0>"

The model is now frozen; version is 2020-02-16.

All the next tasks should be based on this version.

Please review the change log file for the changes and review the model for any errors.

Hilde will use now the master file DDI-CDI_PublicReviewRelease_2020-02-16.eap to update the documentation. Please notice that it is not possible to make any changes to the model while this task.
I can make only very urgent changes after this step.
Then, I can also include diagram folders into the master EA file, if people provide me copies of their EA files.

The 2020-02-16 files are available at: https://drive.google.com/drive/folders/1iy2OpMkMfTx6xuw7BubZIPHxvFVsMGKZ<https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdrive.google.com%2Fdrive%2Ffolders%2F1iy2OpMkMfTx6xuw7BubZIPHxvFVsMGKZ&data=02%7C01%7Clarryhoyle%40ku.edu%7Cf4f7c0cbbf784d1613af08d7b2f5501b%7C3c176536afe643f5b96636feabbe3c1a%7C0%7C0%7C637174638992303749&sdata=zgfpBK%2FSEG2j2cukabv04gF6tyZ%2Fn8nwxH9i5QV4408%3D&reserved=0>

I put now following model identification into the model itself as constants (DDICDI-DataTypes-ModelIdentification):
•        acronym : String [1] = DDI-CDI
•        majorVersion : Integer [1] = 0
•        minorVersion : Integer [1] = 5
•        subtitle : String [1] = Public Review Release 2020-03
•        title : String [1] = DDI - Cross-Domain Integration
•        uri : String [1] = http://ddialliance.org/Specification/DDI-CDI/<https://nam10.safelinks.protection.outlook.com/?url=http%3A%2F%2Fddialliance.org%2FSpecification%2FDDI-CDI%2F&data=02%7C01%7Clarryhoyle%40ku.edu%7Cf4f7c0cbbf784d1613af08d7b2f5501b%7C3c176536afe643f5b96636feabbe3c1a%7C0%7C0%7C637174638992313744&sdata=DxdvQaZ0FPwyZLYqbnc0DffkVE53TzjFn8o0fB6%2BOos%3D&reserved=0>

The URI is used as prefix for the UUIDs in the Canonical XMI.

I didn’t have time enough to simplify the various string types.

I run into an EA issue regarding assigning types to attributes. I wanted to assign a string instead of ValueString to some attributes. EA shows the change, but the exported XMI doesn’t. Only the search type dialog shows in some vague way that the type is not changed. It is necessary to delete the attribute, to create a new one, and to assign a string. I will explore the issue more later. It seems to be only related to the string type.
