HPD Profile• Healthcare Provider Directory (HPD) o HPD Profile is defined by Integrating the Health Enterprise

http://www.ihe.neto Profile specifies a specific implementation of a standard too “supports queries against, and management of, healthcare provider

information that may be publicly shared in a directory structure”

• Technology built on:o LDAP – for data store/data model

openLDAP http://www.openldap.org/ ApacheDS http://directory.apache.org/apacheds/Microsoft Active Directory

oDSML – for APISOAP/XML specification for querying and updating LDAP server http://www.oasis-open.org/committees/dsml/docs/DSMLv2.doc

LDAP Data Model

• Not a relational database

• Limited Query Language

• Quick reads

• Slower writes

• Tree/hierarchy of objects with attributes

Page 4: HPD Overview

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)

Page 5: HPD Overview

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

HPD Profile – Organizational Units• HCProfessional for storing individual provider information

• HCRegulatedOrganization containing information on organizational providers and its relevant information

• HPDCredential to include health related credentials of providers

• Relationship to determine membership

LDAP and Coded Data Lists• LDAP is not relational database

• Many-valued attributes

• How can we best ensure data standardization?

Page 12: HPD Overview

Coded Data Lists in RHEA
