What is the storage backed by CKM?

Is CKM storage is backed by a git repository ?

There is a mirror from the ckm storage to github. https://github.com/openEHR/CKM-mirror
I don’t know about the ckm storage itself. If you want to know: it’s produced by ocean informatics.

Is it open source ? Do we have any open source alternatives for template repositories ?

You’ll find some useful information in the thread “openEHR. How to get started”
Regarding open source backend see this: OpenEHR. How to get started!?

The CKM archetypes and templates are exported to a (configurable) git mirror.
CKM is however not based on this - it is based on an asset management system - which for example enables the versioning etc. of individual archetypes & templates (“assets”) quite nicely.


I see @sebastian.garde has replied about CKM. I agree a simple template repository viewer, preferably open-source and able to talk to git/github repos would be very useful.


Where could the CKM system be downloaded or obtained? Is it free or open sourced?

Ouch, I should have do more homework for this! So sorry.
I’ve NOT been noticed that it’s from Ocean although as a frequent user.

Ocean CKM’s homepage is at:

CKM Installation requirements - openEHR Clinical - openEHR wiki

CKM is a proprietary product. It is not open source.

However all of the archetypes and templates are open source and can be downloaded individually orin bulk (if you have a free account).

The current Trunk versions of all archetypes are also mirrored to Github so you can retreive them from there,

Thanks, Ian.
Yeah, I’ve already downloaded its mirror from github a couple of times.
