Relations between topics

Regarding 2 PfVsTopics which lead to an OpeningTopic

UseCase:
MEP creates 2 topics (PfVs) in his MEP Software. Each of the topics has a BIM-Snippet (IFC Implementing Agreement 157)
The Architecture Software gets this 2 PfVs and creates an OpeningTopic (Solution) from that.

Requirement:
The information that these 2 specific PfVs-Topics lead to that specific Opening must be hold somewhere. MEP needs to know which of his PfVs leads to an opening

Possible Solutions:

• store the GUIDs of the PfVs on the Opening-Topic or store the GUID of the Opening on each PfV-Topic
• additionally add a comment to each PfV-Topic and change the status of them to something like "processed"

I made a proposal to be to discussed in the recently uploaded markup.xsd

This is definitely one of the most important missing features right now.
Other use cases that are common:

• An issue is closed, but another one created because the project team decided the issue will be solved in a different way (a clash is closed without solving the clash, because it is decided to change the design)
• Two issues are merged into one (two are closed, but refered to a new one with a different solution direction)
• and basically all known use cases in source code issue management systems that make this feature so logic that I strongly suggest to implement it.

I agree with berlotti. Related Topic is needed. Adding the direction or parent-child can make it easier to visualize.
I see in the markup also a TopicType in the RelatedTopic. What's that for? It should not have TopicType of the referred topic here causing superfluous info.

Example:
A topic with type "PfV" could have several related Topics; lets say 2 Clashes and 1 Opening. A filter then could be (in words) "Get all clashes (topics) which lead to that PfV.

[ErikPijnenburg]

I understand the related topics. But why the TopicType in the relation?
Above question can also be queried without that redundant info by looking to TopicType of referred topics.

Yes, of course !
I just removed from markup.xsd
