    Selective adoption of DCAM v3 and DAMA-DMBOK2 elements

    Context and Problem Statement

    OPDA’s governance and standards machinery has grown organically:

    • governance.md defines GA / Issuer / Holder / Verifier / TRO roles and the four operational functions (Coordination, Technical Review, Compliance & Risk, Engagement). It is inherited draft technical-scheme material, not evidence of an OPDA-endorsed predecessor scheme.
    • Pages 24, 25, 26 (commit dfcdb08) added Domain Data Stewards, a 12-seat Executive Committee, RACI, SLAs, decision log, and stakeholder engagement modes.
    • Pages 12–16 cover bounded contexts and the PDTF schema corpus (1,538 deduplicated data elements across the base transaction plus 16 canonical overlays).
    • The Conformance Scheme (page 20) treats compliance as binary: a member firm is compliant against a release tag or it isn’t.

    OPDA member firms operate inside organisations that already use industry-standard data management frameworks — most commonly DAMA-DMBOK2 (DAMA International) and increasingly DCAM v3 (EDM Council). These frameworks are the lingua franca for data management conversations with member firms’ data offices, with regulators (FCA, ICO), and with the consumer-advocacy bodies OPDA is engaging.

    OPDA’s framework has not been mapped to either standard. There is therefore no shared vocabulary when a member firm asks “where do the PDTF schema and the developing SPDTF scheme fit in our DCAM assessment?” or “which DAMA knowledge areas does OPDA address?”. The handover dated 2026-05-18 already references DCAM-style stewardship as an aspiration; this ADR makes the alignment explicit and decides how far to take it.

    Decision Drivers

    1. Shared vocabulary with member firms. Most data offices speak DAMA / DCAM. Aligning lowers the translation cost when explaining the transition from the PDTF schema to the SPDTF scheme.
    2. Maturity-based accreditation. Binary pass/fail loses signal. A maturity-scored model differentiates “first attempt” from “operationalised at scale”.
    3. Evidence-based conformance. DCAM’s artifact/evidence discipline pushes vague conformance claims toward auditability.
    4. Filling known gaps. Data Quality and Data Security are weakly addressed today; both frameworks have mature treatments worth borrowing.
    5. Regulator dialogue. FCA and ICO conversations land more cleanly when OPDA’s framework is positioned in their reference frame.
    6. Not reinventing. Where industry has solved a problem, copying is faster and more credible than rolling our own.
    7. Respect DCAM licensing without hiding the lineage. DCAM is a commercial framework owned by the EDM Council. OPDA may freely name DCAM as an inspiration or source across any context (published pages, ADRs, academic papers, member-firm comms, conference talks) — naming is not licensing-protected. What does require a license is verbatim quotation of capability text, sub-capability descriptions, evidence criteria, or maturity-level definitions. See §“Vote and Dissent” newly-resolved #2 for the rationale.

    Considered Options

    • A — Don’t adopt; keep bespoke. OPDA’s framework is substantive and the property-data domain has features (transaction-centric, multi-overlay, statutory data sources like HMLR) that don’t sit cleanly in DCAM/DMBOK’s general-purpose vocabulary. Maintains full sovereignty over framework structure. Loses vocabulary alignment and forfeits the gap-filling shortcut.
    • B — Wholesale adoption of DCAM v3. License DCAM v3 from EDM Council, restructure OPDA’s published framework around the eight components, run member firms through formal DCAM assessments. Maximum vocabulary alignment with finance-sector data offices. High cost: commercial licensing, full restructure of 24+ governance pages, training overhead.
    • C — Wholesale adoption of DAMA-DMBOK2. Restructure the Knowledge Base navigation around the 11 knowledge areas (or the seven in scope for OPDA). Use the DAMA Wheel as the top-level information architecture. Disrupts the current numbered-pages structure that has just been established.
    • D — Selective adoption of specific elements from each (chosen). Adopt the elements that fill identified gaps or align with existing OPDA work, without restructuring around either framework’s top-level taxonomy. Continue to publish OPDA’s framework in its current information architecture, with cross-references to DCAM components and DAMA KAs.

    Decision Outcome

    Chosen option: D — Selective adoption of specific elements from each, because wholesale adoption (B or C) would force restructuring 24+ governance pages without sufficient gain. The frameworks are designed for general data-management organisations; some KAs are genuinely out of scope (operating a DW/BI platform; custodying property data) while others are indirect or adjacent rather than fully N/A (see §“More Information” → “Reassessing the four boundaries”). Selective adoption captures the vocabulary win and the gap-filling win without the restructure cost.

    Adopt the following elements in three waves plus a “genuinely out of scope” list.

    Wave 1 — Vocabulary alignment (low effort, high signalling value)

    Per Decision driver 7 (as revised in the second-pass review — see §“Vote and Dissent” newly-resolved #2), OPDA may name DCAM and DAMA-DMBOK as sources in any context. Only verbatim quotation of capability text, sub-capability descriptions, evidence criteria, or maturity-level definitions requires a license. So Wave 1 labels can carry the source names directly.

    From DCAM v3 (named as source; no verbatim quotation):

    • “Operating Model” as the published name for what /governance/data-stewardship, /governance/meetings-and-feedback, and /governance/stakeholder-engagement describe. DCAM v3’s third component; adopting the name directly. Replaces no content; just labels.
    • “Business Data Knowledge” as the banner for the dictionary / glossary / ontology workstream (/modelling/data-dictionary, /modelling/business-glossary, /modelling/concept-taxonomy, /modelling/ontology, /modelling/shacl-shapes, /modelling/jsonld-mappings). DCAM v3’s eighth component; adopting the name directly. Validates this work as core, not adjacent.

    The “DCAM v3-inspired” or “drawn from DCAM v3” attribution can appear on those pages — page intro / footer — without licensing exposure.

    From DAMA-DMBOK2:

    • DAMA Wheel cross-reference table — for each existing OPDA page, label the DAMA KA(s) it serves. KAs that are genuinely out of scope (operating a DW/BI platform; custodying property data) explicitly disclaimed in a single sentence each. Indirect / adjacent KAs labelled accordingly so the boundary is auditable rather than hidden.
    • Per-KA template — establish a consistent rubric for each page: Purpose · Activities · Deliverables · Roles · Metrics · Maturity. Apply incrementally.

    Wave 2 — Gap-filling workstreams (higher effort, EC sign-off needed)

    Data Quality framework (fills DMBOK KA #11):

    • Owner: Compliance & Risk WG (DQ dimensions map onto UK GDPR Art 5(1)(d) accuracy obligations). Technical WG provides schema hooks and per-overlay validation rules.
    • Adopt the six standard DQ dimensions: accuracy, completeness, consistency, timeliness, uniqueness, validity.
    • Define DQ measurement and reporting for each applicable claim type represented by the PDTF schema or developed for SPDTF.
    • Extend the Conformance Scheme (/governance/conformance-scheme) so a member firm reports a DQ profile, not just a binary compliance flag.
    • New page at /governance/data-quality (placeholder slug — confirm with C&R WG at kick-off).

    Data Security framework (fills DMBOK KA #5 beyond crypto):

    • Owner: Compliance & Risk WG (per governance.md §3.C they already own data-protection impact assessment).
    • Formalise the implicit security controls (issuer onboarding KYC/KYB, DID key management, signature verification, revocation handling) into a named workstream with policy + checklist + audit profile.
    • Anchor on existing compliance-and-policy-checklist.md and Code of Conduct 2026.pdf.
    • New page at /governance/data-security (placeholder slug — confirm with C&R WG at kick-off).

    Maturity-based accreditation — two axes:

    OPDA’s existing Assurance Levels (AL1–AL4) describe the claim; the new capability scoring describes the firm. They are orthogonal, and both are published.

    • Axis 1 — Assurance Level (existing): AL1 self-asserted · AL2 accredited issuer · AL3 accredited issuer with extra controls or proxy authority · AL4 official primary authority. Per-claim property.

    • Axis 2 — Capability score (new): three dimensions scored per capability the member firm claims compliance against:

      • Engagement — governance authority engaged for that capability.
      • Process — process established and repeatable.
      • Evidence — auditable artifacts exist.

      Per-firm property.

    • Each capability gets an Evidence requirement in the Conformance Scheme: what artifact proves the claim.

    • Output: a new Accreditation Directory at /governance/accreditation-directory with per-firm cards showing AL coverage + capability scores. Full spec in ADR-0004.

    • Expected EC discussion at the next quarterly meeting.

    Worked example. Firm X is AL3 + Process 4/6, Evidence 3/6 → high-assurance claims, mid-maturity operations. Firm Y is AL2 + Process 5/6, Evidence 5/6 → medium-assurance claims, mature operations. Both views are useful to a consumer or a regulator; collapsing them into one number loses signal.

    Document-attachment policy for PDTF schema overlays (promoted from Wave 3 — see §“Vote and Dissent” resolved #6):

    • Several v3 overlays carry unstructured attachments today (TA10 plans, EPCs, leasehold packs, photographs) without a published handling policy. Promoted ahead of broader Document & Content work because the artefacts are already in production overlays.
    • Owner: Technical WG (the overlays are theirs) with Compliance & Risk WG input on retention and consent.
    • Define per-attachment-type: file-format requirements, signing / integrity requirements, retention guidance for issuers, consent semantics for consumers.
    • New page at /governance/overlay-attachments (placeholder slug — confirm with Technical WG at kick-off).

    Wave 3 — Adjacent and indirect (monitor, or pick up opportunistically)

    These come from the reassessment in §“More Information”. Each is real OPDA work, but smaller in scope than Wave 2 and not requiring EC sign-off to begin scoping.

    • GARP for OPDA’s institutional records (DMBOK #7 — second strand). Apply GARP principles (accountability, integrity, protection, compliance, availability, retention, disposition, transparency) to the OPDA source tree (markdown, transcripts, briefings, PDFs). Lighter than Wave 2’s overlay-attachment policy — mostly a published handling policy plus retention defaults per source/ subtree. The overlay-attachment strand was promoted to Wave 2 (§“Vote and Dissent” resolved #6).
    • Storage & Operations guidance (DMBOK #4) — retention and disposal. When the Trust Registry moves toward production, publish member-firm retention/disposal guidance for claims represented by the PDTF schema or future SPDTF releases, anchored on UK GDPR retention requirements. Required for the consumer-trust narrative.
    • AI/ML governance over property data represented by the PDTF schema or SPDTF (DCAM Analytics sub-capabilities + Architecture sub-capabilities). Watching brief on ICO and EU AI Act guidance. Bias/fairness considerations specific to property data are non-trivial (historical red-lining patterns embedded in transaction histories). Pick up when the first member firm publishes a model trained on those data and needs a published data-use basis.
    • Data-product discipline for OPDA’s meta-analytics outputs (DMBOK #9 carve-out). Apply data-product discipline (lineage, release plan, versioning) to the Accreditation Directory, Standards Report, Consumer Survey, ecosystem dashboards. Extend provenance-map.yaml toward a lineage dictionary as new reports are produced.
    • Annual EC review of Wave 3 items. ~15-minute agenda item at one EC meeting per year (suggest the one nearest the AGM). Walk each Wave 3 item: has its trigger fired (promote to Wave 2)? Has the item rotted (close out)? Or does the watching brief continue? Belt-and-braces against event-driven triggers that never fire.

    Genuinely out of scope

    • Full DCAM v3 licensing. Cost / process overhead not justified at OPDA’s scale today. Revisit when ≥3 member firms request formal DCAM scoring alignment.
    • Operating a data warehouse or BI platform for OPDA itself. OPDA is a standards body; analytical infrastructure stays with member firms and regulators.
    • Custodying member-firm property data. OPDA never takes possession of property-transaction claims. Trust Registry holds DIDs and revocation lists, not property data.
    • DCAM’s analytics-platform capabilities (model lifecycle, MLOps tooling, feature stores). Even within the AI/ML watching brief above, OPDA scopes only the data-use governance, not the platform engineering.

    Consequences

    • Good, because shared vocabulary with member firms’ data offices and with regulators.
    • Good, because quantifiable maturity story for the Accreditation Directory — a better marketing artefact than a list of binary compliance flags.
    • Good, because identified gaps (DQ, Security) now have framework-anchored remits, not green-field debates.
    • Good, because DCAM’s evidence/artifact discipline pushes the Conformance Scheme toward auditability.
    • Bad, because retrofitting effort. Adding KA labels and per-KA structure to 24+ existing pages is a multi-session task; tempting to do once and drift.
    • Bad, because vocabulary creep. Pulling in framework terms without their full context can introduce ambiguity (“Governance” means different things in DCAM, DMBOK, and OPDA’s own usage).
    • Bad, because Wave 2 expansion. DQ and Security frameworks each merit their own ADR before becoming pages. This ADR commits direction, not page content.
    • Bad, because selectivity drift. Each future contributor will be tempted to pull in additional DCAM/DMBOK elements. The “Genuinely out of scope” list is the hard boundary; Wave 3 is the soft boundary (move items into Wave 2 explicitly rather than letting them drift in).
    • Bad, because Wave 3 expansion ambiguity. Wave 3 items are “monitor or pick up opportunistically” — that wording is permissive and easy to misread as a backlog commitment. Each Wave 3 item has a triggering condition (inline) plus the annual EC review catches drift.
    • Bad, because renumber decoupling. Page numbering was deferred to a separate renumber exercise (§“Vote and Dissent” resolved #4 — subsequently retired by ADRs 0002 + 0003). Risk at the time: Wave 2 drafting stalls waiting for the renumber. Mitigation in place: draft pages under provisional filenames and rename at publication time.
    • Neutral, because Wave 1 (vocabulary) is fully reversible — remove the labels, the substance stays. Wave 2 (DQ, Security, maturity scoring) becomes harder to reverse once the Accreditation Directory uses the new maturity scores; expect member firms to anchor on whatever scoring scheme is published first. Wave 3 items are individually reversible at any time before they become published pages.

    Confirmation

    • Wave 2 (DQ, Security, Maturity Accreditation, Overlay attachments) requires EC ratification before workstream kickoff. Per-wave progress tracked in ADR-0005.
    • Wave 3 review is a standing ~15-minute agenda item at the AGM-adjacent EC meeting (see §“Wave 3 — Adjacent and indirect”). Annual cadence; outputs minuted.
    • Wave 1 vocabulary labels visible in the governance sidebar grouping defined by src/lib/site.ts; “DCAM v3-inspired” attribution discoverable on the named pages.

    Reassessing the four “out of scope” boundaries

    An initial draft of this ADR placed DCAM Analytics Management and DMBOK KAs #4 (Storage & Operations), #7 (Document & Content Management), #9 (Data Warehousing & BI) flatly out of scope. Reviewing each shows the boundary is less clean than that phrase suggests. Three of the four warrant some form of OPDA position.

    DCAM Analytics Management — Adjacent

    • DCAM v3’s eight named components do not include a standalone Analytics component (v2.x had one; v3 folded analytics-and-insights capabilities under Architecture and Business Data Knowledge).
    • Data represented by the PDTF schema is a downstream training corpus. Member firms may use claim history for AVMs, fraud scoring, comparable-sales analysis and market reports. Schema design choices (granularity of fields, time-series capture, comparable inclusions) materially shape what analytics is possible.
    • AI/ML governance is becoming a regulatory expectation (ICO guidance, EU AI Act). The data OPDA standardises feeds into models that affect consumers (valuations, mortgage decisions, listing visibility).
    • Property data has well-documented equity hazards: historical red-lining patterns and pricing distortions can be embedded in transaction histories, then propagated by ML systems trained on them.
    • Position: Adjacent. OPDA does not operate analytics; it shapes the corpus. Watching brief on AI/ML data-use principles for claims represented by the PDTF schema or future SPDTF releases, including bias/fairness considerations specific to property data. Pick up when the first member firm publishes a model trained on those data and a data-use basis is needed.

    DMBOK Data Storage & Operations — Indirect

    • OPDA does not hold member firms’ property data — correct.
    • OPDA does operate trust-registry infrastructure (DIDs, status lists, revocation logs) and the Knowledge Base itself. Both have DBA-style operational requirements: backup, key rotation, availability targets, capacity planning.
    • More importantly, OPDA should publish retention and disposal guidance for member firms holding claims represented by the PDTF schema or SPDTF. UK GDPR requires defined retention policies; “how long does a verified claim live in a member firm’s database after the transaction completes?” is currently undefined. Consumers will ask this. So will the ICO.
    • Position: Indirect. Not a major workstream now. Pick up when (a) the Trust Registry moves to a production-grade deployment and needs a documented SLA, or (b) the consumer-trust narrative needs an answer to “what happens to my data after my house sale?”.

    DMBOK Document & Content Management — In scope

    • DMBOK Chapter 9 covers documents and information in “a range of unstructured media, especially documents needed to support legal and regulatory compliance”.
    • PDTF schema v3 overlays embed document attachments throughout: TA10 fittings & contents, leasehold packs, EPCs, plans, photographs. The base pdtf:Document type carries unstructured payloads alongside structured claims.
    • The Knowledge Base source tree itself is a document and content management system: 200+ markdown files, PDFs of constitutional documents, .vtt meeting transcripts, briefings to government, member-firm communications.
    • Generally Accepted Recordkeeping Principles (GARP) — accountability, integrity, protection, compliance, availability, retention, disposition, transparency — overlap almost perfectly with OPDA’s own published principles in governance.md §1.
    • Position: Should be IN scope. The earlier dismissal was wrong. Promote to Wave 3 with two strands: (1) GARP-based handling for OPDA’s institutional records; (2) document-attachment policy for the overlays that carry unstructured payloads.

    DMBOK Data Warehousing & BI — Mostly out, with a small carve-out

    • OPDA does not operate a warehouse or BI platform. This part of the original dismissal stands.
    • OPDA does, however, produce meta-analytical outputs: the Accreditation Directory, the Spring 2025 Standards Report, the Consumer Survey, ecosystem and conformance trend reports.
    • These deserve BI-style discipline: a published data-product spec per output, lineage from source artefacts, a release plan, versioning. DMBOK Chapter 11’s “Lineage Dictionary” deliverable is close to OPDA’s existing provenance-map.yaml.
    • Position: Mostly out of scope; small carve-out for OPDA’s own meta-analytics outputs as data products with lineage and release discipline. Not a major workstream; extend provenance-map.yaml opportunistically as new reports are produced.

    Commissioned follow-up

    • ADR-0004 — Accreditation Directory spec — commissioned by §“Vote and Dissent” newly-resolved #4 below; covers hosting, scoring granularity, visibility, schema, evidence requirements per score level, naming, and how Maturity Accreditation resolves the parallel-execution cross-dependency with DQ + Security.

    Vote and Dissent

    Resolved during review (2026-05-18)

    The six open questions in the first draft of this ADR were walked through and decided. Outcomes recorded here so the next reader doesn’t re-litigate.

    1. Licensing. Originally resolved 2026-05-18 as “vocabulary-only, never cite”. Revised same day to “permissive: name freely, no verbatim”. Naming DCAM as a source or inspiration is always fine (it’s a fact, not a licensing exposure). Quoting capability text, sub-capability descriptions, evidence criteria, or maturity-level definitions verbatim — or republishing licensed DCAM materials — requires a license. Engagement WG dialogue with EDM Council remains deferred (see “newly resolved” #5).
    2. Maturity scale calibration. Resolved: layer the two axes. AL1–AL4 (per-claim) plus a Capability score with three dimensions (per-firm). See Wave 2 §“Maturity-based accreditation” for the worked example.
    3. Data Quality ownership. Resolved: Compliance & Risk WG owns the framework; Technical WG provides schema hooks and per-overlay validation rules. DQ dimensions sit alongside UK GDPR Art 5(1)(d) accuracy obligations, which Compliance & Risk already covers.
    4. Page numbering. Resolved: renumber the whole governance section as a separate exercise — subsequently retired by ADR-0002 + ADR-0003. This ADR no longer specifies page numbers for new pages; numbers were dropped entirely. The pre-existing 14→30 chain break noted in the 2026-05-18 handover folded into the same migration.
    5. Wave 3 triggering conditions. Resolved: both inline triggers and an annual EC review. Inline triggers for responsiveness; annual review catches drift. See the “Annual EC review” item in Wave 3.
    6. PDTF schema overlay attachment policy. Resolved: partial promotion. The overlay-attachment strand moved to Wave 2 (artefacts are already in production overlays). The GARP-for-OPDA-records strand stays in Wave 3.

    Newly resolved during review (2026-05-18 second pass)

    The four newly-surfaced questions were walked through and decided. Plus a follow-up on item #1 (Licensing) that softened the original “vocabulary-only” stance.

    1. Scope and ordering of the governance-section renumber. Resolved: drop numbering entirely. Addressed by ADR-0002 (folder hierarchy and slug taxonomy) + ADR-0003 (idiomatic Astro refactor) — both implemented 2026-05-18. URLs are now bare slugs (/governance/data-stewardship), no numbering, sidebar ordering controlled by src/lib/site.ts. Renumber question can never recur.

    2. DCAM attribution boundary. Resolved: permissive — name freely, no verbatim. Naming DCAM is always fine in any OPDA context (KB pages, ADRs, academic papers, EC meeting papers, member-firm comms, conference talks, regulator submissions). Quoting capability text, sub-capability descriptions, evidence criteria, or maturity-level definitions verbatim requires a license; same for republishing any DCAM-licensed material. This supersedes the originally “vocabulary-only” reading of the original Q1 — see Decision driver 7 (revised) above. The line is the line drawn by copyright law: cite freely, don’t reproduce.

    3. Wave 2 timeline. Resolved: all three workstreams in parallel from day 1. Compliance & Risk WG runs DQ + Security + Maturity Accreditation simultaneously. Technical WG runs the Overlay attachment policy independently. Pre-condition: Engagement WG to recruit additional C&R members from firms with mature internal DQ / Security functions (large lenders, surveyors, conveyancing platforms) before workstream kick-off. Trade-off accepted: maximum velocity at the cost of recruitment dependency. Maturity Accreditation will need to specify dimensions with placeholders for DQ + Security content that ships in parallel — see ADR-0004 (commissioned) for how the spec resolves the cross-dependency.

    4. Annual EC review slot. Resolved: EC meeting nearest the AGM. Pairs the Wave 3 review with the annual governance moment (annual report, member ratifications). Q1 / Q4 depending on AGM date. Action: add the 15-minute Wave 3 review item to the AGM-adjacent EC meeting’s agenda template.

    5. DCAM licensing dialogue with EDM Council (follow-up to item #1). Resolved: stay deferred. Re-evaluate if a member firm asks for formal DCAM alignment, or if an academic paper / regulator submission directly references the framework, or if OPDA’s Accreditation Directory would benefit from EDMC endorsement.
