  2. HPD Profile • Healthcare Provider Directory (HPD) • HPD Profile is defined by Integrating the Health Enterprise http://www.ihe.net • Profile specifies a specific implementation of a standard to • “supports queries against, and management of, healthcare provider information that may be publicly shared in a directory structure” • Technology built on: • LDAP – for data store/data modelopenLDAP http://www.openldap.org/ApacheDS http://directory.apache.org/apacheds/Microsoft Active Directory • DSML – for APISOAP/XML specification for querying and updating LDAP server http://www.oasis-open.org/committees/dsml/docs/DSMLv2.doc

  3. LDAP Data Model • Not a relational database • Limited Query Language • Quickreads • Slower writes • Tree/hierarchy of objects with attributes

  4. LDAP Terminology - LDIF • LDIF – line delimited interchange format dn: cn=Robert Smith,ou=people,dc=example,dc=com objectclass: inetOrgPerson cn: Robert Smith cn: Robert J Smith cn: bob smith sn: smith uid: rjsmith • dn (distinguished name) is the location of the record in LDAP.read it right to left to walk down tree • objectClass defined the object being stored. Properties/attributes of an object class defined in ldap schema • Remainder are attributes. May be multi-valued (e.g. cn)

  5. LDAP Terminology - Schema • Schema used to define attributes of object class objectclass     ( 2.16.840.1.113730.3.2.2    NAME 'inetOrgPerson'    DESC 'RFC2798: Internet Organizational Person'SUP organizationalPerson    STRUCTURAL        MAY (                audio $ businessCategory $ carLicense $ departmentNumber $                displayName $ employeeNumber $ employeeType $ givenName $                homePhone $ homePostalAddress $ initials $ jpegPhoto $                labeledURI $ mail $ manager $ mobile $ o $ pager $                photo $ roomNumber $ secretary $ uid $ userCertificate $                x500uniqueIdentifier $ preferredLanguage $                userSMIMECertificate $ userPKCS12         )) • Inherit attributes of superior class • Attributes defined globally in schema with data typ http://www.zytrax.com/books/ldap/ape/core-schema.html#organizationalperson

Coded Data Lists in RHEA • RHEA PR stored coded facilities, standardized data lists #provider dn: nid=10222034995, ou=Providers, dc=moh, dc=gov, dc=rw objectclass: providerPersonnid: 10222034995cn: Chilboa Rainda#and their positingdn: ou=facility|372, nid=10222034995,ou=Providers, dc=moh, dc=gov, dc=rw objectclass: providerPostou: facility|372 #coded facility from Master Facility Listdescription: KatabagemuemployeeType: post_type|pps #coded type of employeelocationCode: county|AU050204 #coded municipality of deployment
