Provider Registry and the HPD Profile

This page is to consolidate information about the HPD profile for implementation in the RHEA Provider Registry as we evaluate which technologies to use in Rwanda in as part of the Track 2 RHEA profile.

DSML

DMSLv2 is the XML format required by HPD to make queries and updates of the LDAP server

• XSD to validate a DSML document
• HPD Query Examples File:58-Provider Information Query - Req and Response HPD Examples.pdf
• HPD Feed Examples File:59-Provider Information Feed - Req and Ack HPD Exampels.pdf

LDAP+DSML Servers and DSML Gateways

There are several DSML gateways we can use to translate DSML to LDAP queries as well as LDAP servers that support DSML directly. Here is a listing:

• JavaLDAP
• OpenDS
• OpenDJ
• ApacheDS (not sure if does support DSML natively)

Note: we are currently using OpenLDAP as our LDAP server.

Evaluation Criteria

Here are some of the criteria to evaluate the DSML gateways / LDAP+DSML servers

• Server Type (DSML gateway vs. LDAP server with native DSML support)
• Open Source License
• Documentation Updated
• Active Development
• Ease of installation
  • Availability on standard Linux platforms
  • Requirements for configuration
• Speed/Performance Issues
  • Memory Usage
• Ability to validate incoming DSML messages. Example validations:
  • does the hcidentifier attribute meet our format (e.g. hcIdentifier="id_type:id_number")
  • can we validate coded lists (e.g. facility code)
