RE: [office-collab] Additional use case for change tracking

I’ve attached a document with these two cases. Robin’s caveat applies here as well – hand-crafted markup and it’s been a year and a half since I first wrote this up, so please excuse any minor errors. Please note I’ll be away for a week and a half starting tomorrow, Friday afternoon.

As I note in the doc, I see the second as the same as the first. The discussion around whether the document is or isn’t saved, etc. seems to me to conflate file format definition with runtime behavior. An implementation can choose how to make use of the file format constructs as it sees fit for its particular usage scenarios. The attached doc points out a couple instances where implementations could approach the cases different and end up with different markup than that shown.

For example, each change could be captured as markup at the time the change is made, regardless of author or session state. Or, a change by one author further changed by that same author could omit the interim state to simplify the markup, and this could further be dependent on whether the subsequent change is made in the same session as the prior change. And what demarcates a session – saving the document, closing the document/app, something else? An implementation might even choose to roll up all changes by one user during a session into a single text:changed-region (rather than one per user action), with each change (user action) listed underneath as individual atomic changes.

I’ve been away since June 13 and am still catching up on a three-week pile. I’m out for a week and a half again starting the end of this week. I’ll try to look into this, but can’t make a definite promise just yet.

Haven’t we already looked at nested changes? For example, the original ECT proposal doc had an example on multiple formatting changes and the supplement doc added cases under the Compound Changes section such as “add text, format it, delete it”.

Patrick - thanks for your clarification, I did interpret it correctly and will post a GCT solution in a following email

Patrick,

Thanks for these examples - I think it would help if we all encoded exactly the same sample, so here is my suggestion (which is subject to your approval that I have interpreted your cases correctly)

1st Case

1. Original saved by 1st author
<text:p>This is the original paragraph, created with change tracking on so seen as an added paragraph.</text:p>

2. 2nd author changes text:
<text:p>This is the second version of the paragraph, created with change tracking on so seen as a modifed paragraph.</text:p>

Transferred back to 1st author, but that is not a further change.

2nd case

1. Original
<text:p>This is the original paragraph, created with change tracking on so seen as an added paragraph.</text:p>

2. 1st author changes text:
<text:p>This is the original paragraph, created with change tracking on so seen as an added paragraph, which is then modified.</text:p>

3. 1st author changes text again:
<text:p>This is the modified paragraph, created with change tracking on so seen as an added paragraph, which is further modified.</text:p>

Are these specific examples OK?

Yes, with the understanding that the second example should reflect a manual "save" event that fixes the text that is then subject to change tracked modification.

In other words, if in a single editing session, with no saves, I type:

Here is the incorrect text.

and seeing I have made a mistake I move the cursor and reform the text to read:

Here is the correct text.

There should be no change tracking recorded because I am in a single editing session.

Or did I succeed in making the use case less clear?

Thanks!

Hope you are having a great day!

Patrick
