How many FOLDER trees can be associated with the same EHR at the same time? In other words, EHR 0…1 FOLDER_tree OR EHR 0…n FOLDER_tree? Figure 20. High-level Structure of the openEHR EHR [image] This figure seems to imply a single EHR could have more than one folder trees at the same time. F…

[image] linforest: Especially the cardinality of the attribute folders, 0…1, looks strange for me. I think you find this strange because what you have circled is NOT the cardinality, but just the existence (or occurrences) of the folders attribute, i.e. folders may or may not exist (aka is o…

You can see here that EHR.folders has cardinality *.

The directory endpoint access the directory of the ehr which is the first folder : EHR Information Model openEHR EHR Information Model specification " directory: Optional directory structure for this EHR. If present, this is a reference to the first member…

Thank you very much, @thomas.beale and @stefanspiska . Forgive me please. Honestly, I’m still confused about: What kind of folder hierarchy a single EHR can have, i.e., mono-/multi-hierarchy? What is the relationship between directory and folders? Two separate but related attributes of the EHR clas…

Directory is just a reference to folders[0] So post Directory is create folders[0] which gives you an error if already exist. I belive at one time only Directory existed and folders was added late and then Directory became simple folders[0] die first element in the list.

[image] stefanspiska: Directory is just a reference to folders[0] Thanks, @stefanspiska . I see, it’s a reference relationship. For folders[0], the index [0] means threre can exist more than one folder tree side-by-side?

Another confusing stuff for me is: there is no POST /Update/Delete operations for folders on the openEHR Tool UI: <li class="nav-item dropdown dropend"> <a class="nav-link dropdown-toggle" href="#" data-bs-toggle="dropdown" > Directory </a> <ul cl…

[image] sebastian.garde: NOT the cardinality, but just the existence (or occurrences) of the folders attribute Indeed, I was confusing the two attributes of the EHR class with the “physical” folder structures. @sebastian.garde Thanks a lot for your clarification.

[image] linforest: Now I can understand the 409 error above because I was trying to POST a second directory, violating its cardinality 0…1. Am I correct? That 0…1 means optionality, not cardinality. It means there could be not even a folders container. if there is something there, it is a Lis…

Some other useful info: the EHR.folders was added in RM 1.1.0, previously we only had EHR.directory. The REST specs is lagging behind, as it does not have yet operation for folders. What you see there ion EHRbase is just the REST for directory “resource”. This missing piece of specs is anyway planne…

It gets vividly clearer and more interesting. Thank you so much, @thomas.beale and @thomas.beale .

Folders allow grouping of Composition into logical groups so yes you could use that to modele say a episode of care see: Representation of Episodes of Care and Encounters in folders
