Preventing new data silos takes more than buying a catalog or publishing a sharing policy. Give governance enterprise authority, assign accountable owners and stewards, document and inventory data in common formats, and make interoperability and controlled sharing part of routine project and system decisions. These settings work together: data must be discoverable and usable, but access still needs privacy, security, and disclosure protections.
Start with authority and named accountability
Give a governance body or accountable executive the authority to set organization-wide rules and resolve disputes between domains. For each important data asset, name a business owner and a data steward; define what custodians and users are responsible for as well. Assign staff time and funding to maintaining definitions, quality expectations, access rules, and documentation. Without authority and people responsible for applying the rules, standards can exist on paper while teams continue building isolated systems.
Oregon offers a concrete public-sector example, not a universal template. Its statewide policy took effect in March 2022 and calls for agencies to appoint a Lead Data Steward and submit a Data Governance Plan every two years to the Chief Data Officer. Federal Data Strategy guidance likewise emphasizes adequate authorities, roles, structures, policies, and resources. Organizations should adapt the pattern to their own law, risk, architecture, size, and users. Oregon’s Data Governance Policy and the Federal Data Strategy practices describe these approaches.
Make existing data discoverable and understandable
Maintain a searchable inventory of data assets, with metadata sufficient for people to identify what exists and whether it fits their needs. Keep documentation current and accessible, including definitions, provenance, quality information, schemas, and data dictionaries. An inventory that lists a dataset but omits its meaning, limitations, or responsible contact may not enable safe reuse.

For U.S. federal agencies, the Federal Chief Data Officers Council announced DCAT-US v3.0 implementation guidance on August 21, 2026, as a way to standardize metadata for agency inventories. The council characterizes the guidance as initial and iterative, not a final, universal playbook. The council’s DCAT-US resource is specific to that federal context; organizations elsewhere should select metadata conventions appropriate to their communities and systems.
Set shared standards and require interoperability
Adopt or adapt common standards with the relevant communities of interest. Require systems to support interoperable access and extraction in usable formats, and keep data separable from application layers where that fits the architecture. Make schema documentation available across teams so that shared data can be interpreted consistently.

Oregon law illustrates how these requirements can be made concrete in public-sector systems: it addresses approved standards, common and extensible metadata, interoperable systems, inventories, and shared schemas and dictionaries for relevant state-agency systems. These statutory requirements apply in Oregon, not automatically to other organizations. Oregon Revised Statutes, Chapter 276A provides the jurisdiction-specific detail.
Formalize sharing between teams
Use written agreements when data crosses team or organizational boundaries. State the purpose and permitted uses, distribution conditions, participant responsibilities, liability or other legal terms, and exchange conditions. Create cross-functional councils or communities to coordinate definitions and processes that span domains.
Sharing can help avoid duplicate collection and management, as well as conflicting copies of a dataset. A Federal Highway Administration report describes agreements as a way to establish the terms of exchange and support sharing across organizations. Its report dates to December 2016, so treat it as guidance on agreement mechanics and rationale rather than a current, universal policy mandate. FHWA’s report on data sharing discusses these practices.
Make access controlled, not indiscriminate
Discoverability does not mean every person should be able to open every dataset. Define access tiers or permitted purposes, the roles responsible for granting access, and applicable privacy, confidentiality, security, and rights requirements. Include a release review for disclosure risk where data will be made public or shared more broadly.
Federal strategy guidance couples data sharing and broad access with protections for privacy, confidentiality, proprietary interests, and disclosure risk. Oregon law also calls for privacy and confidentiality protections and proper security. The appropriate controls depend on the data and governing rules; the goal is to enable legitimate use without treating openness as unrestricted access. Federal Data Strategy practices and Oregon Revised Statutes, Chapter 276A set out these principles.
Build governance into the data lifecycle
Apply governance requirements when projects are planned, systems are procured or modernized, agreements are negotiated, and data is managed in routine operations. Revisit the inventory and policies periodically, assess maturity, train staff, and ensure stewards have the time and resources to carry out their responsibilities. Otherwise, new projects can recreate isolated definitions, formats, and access arrangements even when an organization has enterprise policies.

Oregon’s biennial plan requirement is one example of a recurring review cadence. Federal guidance calls for maturity assessment and long-term resource planning. The right schedule and level of formality will vary; no cited source establishes one configuration that works for every organization. Oregon’s policy page and the Federal Data Strategy practices provide examples.

The cited public-sector sources do not rank products or prescribe a single implementation. When comparing an approach, program, or platform, assess whether it can support:
- Clear enterprise authority and a workable way to resolve cross-domain disputes.
- Named ownership and stewardship across domains.
- Broad inventory coverage, useful metadata, and effective search.
- Shared schemas, standards, documentation, and interoperable exchange.
- Role- or purpose-based access, auditability, privacy, and disclosure-risk controls.
- Integration with current architecture and governance requirements in procurement and agreements.
- Realistic staffing, cost, training, and maturity-review demands.
These are practical decision criteria derived from the governance requirements above, not a vendor ranking or a claim that one tool alone prevents silos. The cited material establishes practices and requirements, not a measured percentage reduction in silo formation.
