* [Different approaches to Interoperability](https://www.evernym.com/blog/getting-to-practical-interop-with-verifiable-credentials/) by Daniel Hardman of Evernym
> Several VC ecosystems have grown up around the VC spec. Each touts standards compliance and interoperability, yet they do not currently interoperate with one another. Let’s have a look at their differences and commonalities, and then explore a simple proposal that might make which language your VCs “speak” as transparent as which language you choose when you watch a movie.
* [DHS/SVIP Interoperability Plug-Fest 2 : Features Under Test ...](https://lists.w3.org/Archives/Public/public-credentials/2021Mar/0022.html) John, Anil
As you know, we had our first Interop plug-fest last year in May 2020, which was a heavy lift for our portfolio companies -- To be blunt, while there was a lot of hand-waving on interop, that was the first time anyone had demonstrated any manner of concrete cross-vendor / cross-platform interop in the VC/DID community.
This presentation on the DHS/SVIP Interop Plug-Fest is epic!

> ([slides](https://docs.google.com/presentation/d/1MeeP7vDXb9CpSBfjTybYbo8qJfrrbrXCSJa0DklNe2k/edit%23slide%3Did.p1) Through the presentations and demos, we hope that you are able to gain an appreciation of the engineering depth, openness, inclusiveness and the multi-vendor, multi-platform interoperability that we demonstrated that is needed for these type of solutions to internet scale without locking anyone into a particular vendor or technology stack.

> [Interoperability](https://medium.com/transmute-techtalk/the-business-case-for-interoperability-a1a2b884297d) moves from theory to reality when companies have meaningful ability to choose. It is predicated on open standards foundations that enable easy movement of data and vendors.

DHS SVIP has been leading the charge on interoperability for years now, putting their funding and networks on the table to lead the charge.

These will probably always differ and make a universal abstraction impossible; and that’s not a bad thing! These requirements are always going to be specific to each regulatory context, and without them, innovation (and large-scale investment) are endangered by regulatory uncertainty.

The Interoperability working group will be tracking them and providing guidance and documentation where possible. Importantly, though, there is a new DIF Working Group coming soon, the Wallet Security WG, which will dive deeper into these profiles and requirements, benefiting from a narrow scope and IPR protection, allowing them to speak more bluntly about the above-mentioned details.

After a public review period during June with stakeholders in air travel, government, healthcare, hospitality, and other affected sectors, the Blueprint was finalized in mid-July for final approval and publication. “Publication of the V1.0.0 Blueprint is just the first step in seeing interoperable privacy preserving digital health passes adopted in order to support people being able to gather together again with lower personal and public health risk,” said Kaliya Young, chair of the Working Group and Ecosystems Director at CCI. “Our next task is collaborating with real world implementers to fill in any remaining gaps to get to an interoperable system and working with LFPH and other partners to deliver open source code that can be deployed.”

Accurate labeling, interoperability profiles, and testing are urgently needed to drive interoperability and scale decentralized identity, says a new [white paper](https://indicio.tech/wp-content/uploads/2022/03/Indicio_Report_TrustVerifiableCredentialsInteroperability_033022.pdf) from Indicio
Seven aspects of interoperability
1. DID methods
2. Content encryption key types
3. Communication protocols
4. Credential format and signature types
5. Credential access / storage (wallet)
6. Credential protocols and coordination formats
7. Compatible governance / trust

The lines of action of the laboratory are framed in six blocks: resilient water resources, the impact of global change; efficient infrastructure management; the environment and health; water and energy; and water demand management. The projects developed contribute to the achievement of one or more Sustainable Development Goals, putting the citizen at the center of digital transformation and advocating a perspective on technological humanism.
