Overview

The Metadata Sharing Module allows all kinds of metadata (concepts, htmlforms, locations, roles, programs, etc.) to be exchanged between different OpenMRS installations. It supports metadata defined in the core as well as in modules provided appropriate handlers are registered. Conflicts between local and incoming metadata can be identified and resolved. The module can be used both through an API and a web interface.

Any dependent metadata will be packaged along with the selected item. For example, if you select a concept which has coded answers, it will package the initial concept along with all the coded answer concepts, class and datatype. If you select an htmlform, it will package the form along with the encounter type, all concepts used on that form, etc.

Planned features:

Installation

Download and install the latest version (v1.3).

Download older versions from the module repository.

Requirements

1.x

This version to work correctly requires OpenMRS 1.9.1, 1.8.4, 1.7.4 or 1.6.6. Packages exported with this version are not backwards compatible. Packages exported with previous versions cannot be imported with this version.

0.10.x

This version will work correctly with the same OpenMRS versions as version 0.9.x. Packages exported with this version are entirely compatible with 0.9.x.

0.9.x

For the module to work correctly you need to run OpenMRS in either of the following versions: 1.6.4 Build 21295+, 1.7.3 Build 21294+, 1.8.1 Build 21293+.

As of the 0.9 version of the module to import/export HtmlForms you need HtmlForm Entry Module in version 1.8 or later.

0.8.x

OpenMRS 1.6.3+ (1.7.x and later were not tested)

In order to import/export HtmlForms you need HtmlForm Entry Module in version 1.7.2.

Troubleshooting

1. MySQL error ‘Packet too large’ – set MySQL variable max_allowed_packet=16M details

2. Import fails with ConcurrentModificationException and the following stack trace:

   SEVERE: Servlet.service() for servlet openmrs threw exception
   java.util.ConcurrentModificationException
   	at java.util.HashMap$HashIterator.nextEntry(HashMap.java:793)
   	at java.util.HashMap$KeyIterator.next(HashMap.java:828)

   	at org.openmrs.api.handler.ConceptNameSaveHandler.handle(ConceptNameSaveHandler.java:37)

   It is a known bug in OpenMRS (TRUNK-2428). You need to update OpenMRS and use one of recommended versions (see #Requirements).

3. Import fails with Column 'concept_name_id' cannot be null:
