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.

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

The module is under heavy development and it is best to use the latest available version with all bug fixes.

Download older versions from the module repository.



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.


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.


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.


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.


  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
    	at java.util.HashMap$HashIterator.nextEntry(
    	at java.util.HashMap$
    	at org.openmrs.api.handler.ConceptNameSaveHandler.handle(
    	at org.openmrs.api.handler.ConceptNameSaveHandler.handle(

    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:

    You need to upgrade OpenMRS to 1.9.1 rev:28634, 1.8.4 rev:28650, 1.7.4 rev:28651, 1.6.6 rev:28652. See TRUNK-3626.

  1. Can someone please add a few paragraphs on how to use this module.  Thanks.

  2. Rafal, great job getting lots of documentation up here. I would suggest breaking this up into several pages:

    1. Overview
    2. Users Guide
    3. Technical details
  3. Can you start a release notes section that you keep up with the different changes in each version? See the formentry or sync module pages for examples.

  4. user-db8b0

    Should it be mentioned under the "Requirements" section that the Metadata Mapping module first needs to be installed and running before the Metadata Sharing module can run?
