Across the world, registers underpin some of the most important functions of governments, economies and societies. They establish and maintain trusted information about companies, beneficial ownership, property, licences, securities, citizens and countless other entities and rights.
Yet many of these registers still operate independently.
As governments accelerate digital transformation and economies become increasingly interconnected, simply digitising registry information is no longer enough. The next challenge is enabling registers and the systems around them to communicate, understand and trust information across organisational and jurisdictional boundaries.
This is where interoperability becomes critical.
True registry interoperability goes beyond connecting systems or exchanging data through an API. It requires a shared understanding of what information means, where it comes from, how authoritative it is and under what conditions it can be exchanged and reused.
For registry operators, this creates an important question: is your register ready to participate in an interoperable world?
Interoperability does not mean replacing your registry system, surrendering control of your data or adopting the same technology as everyone else. It means preparing your register and your organisation so that trusted information can be understood, accessed and exchanged more easily with other authorised systems when required.
Here are five areas registry operators should consider.
1. Understand your data
Before registry data can be exchanged effectively, you need a clear understanding of the information your register holds.
What are your core data entities? How are they defined? Which identifiers do you use? What events change the information in your register? Which data is authoritative, and which information is supplied by other parties?
These questions may sound straightforward, but different registers can use different terminology and structures for similar information.
Understanding and documenting your data is therefore an important first step towards interoperability. It makes it easier to map information to common definitions, standards and data models without requiring your register to operate in exactly the same way as another.
Interoperability does not require registers to become identical. It requires them to understand one another.
2. Know the authority and provenance behind your data
Registry information has value because of the authority behind it.
When information moves beyond your register, however, some of that context can easily be lost.
Other organisations need to understand where information originated, who maintains it, when it was updated and what level of confidence or legal effect can be attached to it.
Registry operators should therefore consider how provenance and authority can travel with the data they make available.
Is information verified by the registry or provided through self-declaration? Is the register legally authoritative for that information? When was the record last updated? Has its status changed?
Making this context clear allows other systems and organisations to use registry information appropriately and with greater confidence.
3. Make your data accessible in a structured way
Having a digital register does not automatically make it interoperable.
Information may be available through a website or search portal while still being difficult for another system to access, interpret and process.
Registry operators should consider how appropriate information can be made available in structured, machine-readable formats and how authorised systems could interact with that information.
Depending on the registry environment, this could involve APIs, data services or other secure exchange mechanisms.
The objective is not simply to expose more data. It is to make appropriate registry information easier to exchange reliably, consistently and securely when there is a legitimate need to do so.
For some registries, this may require technical development. For others, the first step may be identifying where existing systems create barriers to data exchange and establishing a roadmap for addressing them.
4. Establish clear rules for sharing and accessing data
Technical readiness is only one part of becoming interoperable.
Registry operators also need to understand the legal, operational and governance conditions under which their information can be exchanged.
Which information is public? Which information is restricted? Who is authorised to access it? For what purposes? What legal or regulatory requirements apply when information is shared with another organisation or jurisdiction?
Clear policies around access, privacy, security and data responsibility make it easier to participate in trusted data exchange.
This becomes particularly important when interoperability crosses borders, where jurisdictions may have different legislation, privacy requirements and approaches to registry information.
Preparing for interoperability therefore requires conversations beyond the technology team. Legal, policy, operational, security and registry specialists all have a role to play.
5. Build interoperability into your organisation
One of the biggest barriers to interoperability may not be technology at all.
Registry organisations need the capability to collaborate with other registers, government agencies, standards bodies and technology partners.
That means establishing ownership for interoperability, understanding relevant standards and initiatives, and ensuring technical, operational and policy teams can work together when opportunities for data exchange arise.
It also means considering interoperability whenever registry systems are modernised, upgraded or replaced.
Every registry modernisation project is an opportunity to ask:
Will this make it easier or harder for our register to exchange trusted information in the future?
Making interoperability part of technology strategy, procurement and registry modernisation can help prevent today’s decisions from becoming tomorrow’s barriers.
You do not need to transform everything at once
Becoming interoperability-ready is a journey.
Registers operate in very different environments. They have different legislation, technologies, resources, operating models and levels of digital maturity.
A register does not need to replace its core platform or redesign its entire organisation before it can begin preparing for interoperability.
The starting point is understanding where you are today.
How well documented is your data? How easily can it be mapped to external standards? Can authorised systems access information in structured formats? Is provenance clear? Are your access and sharing rules defined? Does your organisation have the governance and capability to participate in data exchange?
Answering these questions can help registry operators identify practical steps towards greater interoperability.
Preparing for a more connected registry ecosystem
The future of registry interoperability is not about creating one global register or forcing every jurisdiction into a single technology model.
It is about enabling independent registers to participate in trusted networks where information can be discovered, understood, verified and exchanged when required, while registry operators maintain control over their own systems, data and regulatory responsibilities.
For registry operators, preparing for that future means making interoperability part of the way they think about data, technology, governance and modernisation.
GRX is focused on helping create the conditions that make trusted registry interoperability possible, bringing together registry expertise, shared frameworks and approaches that can make it easier for registry organisations to participate in a more connected global ecosystem.
The opportunity is to start preparing now.
Because the question is increasingly moving from whether registers will need to interoperate to how ready they will be when the opportunity to connect arrives.
