This schema is based on minimal standard metadata, with additional name value pairs in the Reference ID fields to hold some or all of the following:

  • Specialties (hierarchical and potentially multiple)
  • References to "content" - such as PRSB sub-headings
  • Pathway ID
  • Episode, spell IDs etc. (as used in mental health/community)


Metadata summary # = searchable
Generic Requirement Suggested XDS implementation
Patient demographics (global# and local IDs) Standard XDS usage - Patient ID and source Patient info
Overall Coded Document Classification Class Code (source TBD) & Type Code (from SNOMED "correspondence document type" subset)
Author(s)& Authenticator Standard XDS representation, including person (name), role, specialty and institution & Legal Authenticator
Context * Environment Healthcare Facility Type Code & Practice Setting Code
Human readable summary for visual scanning Title & Comments
Low level technical representation, location, Date time etc.
  • Format Code,
  • Mime Type
  • Availability Status
  • Creation Time
  • Entry UUID
  • Hash
  • Size
  • Home Community ID
  • Repository Unique ID
  • UniqueID
  • URI
  • Language Code
  • Service Start Time
  • Service Stop Time
Confidentiality requirements Confidentiality Code
Specialty-specific codes (e.g. modality/procedure/body part for radiology, or operation code for surgery) EventCodeList
Speciality/"treatment function code"/"folder" - see note 1. ReferenceIdList with multiple key-value pairs (in reality, coded values) - e.g.
  • "Specialty=Surgery"
  • "Specialty=Orthopaedic Surgery"
  • "Specialty=Hip Surgery"
Administrative "links" - e.g.
  • accession number (lab and radiology)
  • Pathway ID
  • Visit and Episode IDs (mental health)
ReferenceIdList with key-value pairs (in reality, coded values)- e.g.
  • Accession Number = 12345
  • Episode Number = ABC-1243-99
Contents included - see note 2. ReferenceIdList with multiple key-value pairs (in reality, coded values)- e.g.
  • SubSectionType = History
  • SubSectionType = Problem List
  • SubSectionType = Drugs on Discharge

Notes:

1 - Specialty
This is emerging as one of the most important search fields, and as shown in DocMan may need to have a different level of granularity for different users.
2 - Content
This would share codes with the PRSB headings/sub-headings to allow a user to locate a document which contains a particular type of data, irrespective of the document's nominal type.
