Help in building templates

Hi,

My name is Nicola Onano.
I work for CRS4, a not-for-profit research center in Cagliari (Italy).
My group is interested in the openEHR project. Our aim is to build EHRs in collaboration with “Ospedale G. Brotzu” (a public hospital, here in Italy).
I studied the openEHR project, I found it very interesting and I appreciated the ease of use of the archetype editor developed by Ocean Informatics.
On the other hand, I can’t understand how to create a template from single archetypes, how to build the skeleton of an EHR, and I can’t find any documentations that explain it.
Do exist any example templates or example EHRs available for beginners?
In the web sites www.openehr.org and www.oceaninformatics.biz I read about a template designer developed by Ocean Informatics, but it doesn’t seem available.
Does it exist any freeware/Open Source template designer?

Please, can someone help me?

Sincerely

Nicola Onano
