LinkedIn Post — Draft#

Posting: Tuesday 15 April 2026, morning, Singapore time (before API Days Singapore Day 1)

Option A: Professional + personal (recommended)#

I’m excited to announce that OpenInherit — the open estate data interchange standard — has partnered with Juan Cruz Viotti and Sourcemeta for schema tooling, validation, and governance.

For those who don’t know Juan: he’s the co-author of Unifying Business, Data, and Code (O’Reilly), a leading voice in JSON Schema, and the creator of Sourcemeta — the toolchain we use to validate, lint, bundle, and test every one of INHERIT’s 31 entity schemas, 21 jurisdiction extensions, and 2,000+ test cases.

Estate planning data has been trapped in PDFs, Word documents, and proprietary systems for decades. INHERIT gives it a shape — JSON Schema 2020-12 — so that when life changes (marriage, moving country, new children), software can programmatically answer: what happens to the existing will?

The standard now covers 7 legal traditions (common law, civil law, Islamic, Hindu, Jewish, customary, and mixed), with extensions for Singapore, Malaysia, India, Japan, PRC China, Australia, the UAE, and 14 more jurisdictions. This week we shipped v6.4 with 53 schema improvements — including structured bequest-asset linking, powers of appointment, executor powers, and typed survivorship conditions — all validated by Sourcemeta’s toolchain.

I’m here at API Days Singapore this week presenting INHERIT for the first time. If you’re at the event, I’d love to show you what happens when you upload a real will and watch structured data emerge from a PDF.

The standard is open source, Apache-2.0 licensed, and available now:

• GitHub: github.com/openinherit/standard
• Developer docs: dev.openinherit.org
• npm: @openinherit/schema | @openinherit/sdk

Thank you Juan, Cassian Smith, and the JSON Schema community for making this possible.

Option B: Shorter, more punchy#

Estate planning data has been trapped in PDFs for decades. Today we’re changing that.

Announcing the partnership between OpenInherit and Sourcemeta — Juan Cruz Viotti’s JSON Schema toolchain that validates, lints, and bundles every schema in the INHERIT open estate data standard.

31 entity schemas. 21 jurisdiction extensions. 7 legal traditions. 2,000+ tests. One open standard for wills, trusts, and estates — across common law, civil law, Islamic, Hindu, Jewish, customary, and mixed systems.

v6.4 just shipped with 53 improvements. Here at API Days Singapore this week to show it live.

Option C: Story-led (the will that started it all)#

A jade bangle changed everything.

When I tried to model a Singapore will in JSON — a simple bequest from an aunt to her niece — I discovered that no open data standard could express the relationship. The schema literally didn’t have a word for “aunt to niece.”

That was 6 days ago. Since then, working with the JSON Schema toolchain from Sourcemeta (created by Juan Cruz Viotti, co-author of Unifying Business, Data, and Code), we’ve shipped:

• 53 schema improvements across 31 entity types
• A new PowerOfAppointment entity
• Typed survivorship conditions, executor powers, and statutory exclusions
• 21 jurisdiction extensions covering Islamic faraid, Hindu coparcenary, Jewish halachic succession, and more
• 10 test wills spanning Singapore, England, France, New York, Michigan, Taiwan, Philippines, Australia, India, and Nigeria

The standard is called INHERIT — an open, Apache-2.0 licensed data interchange format for estate planning. It turns the world’s most important family documents into structured, machine-readable data.

I’m at API Days Singapore this week to present it. Bring your will. If INHERIT can’t model it, I’ll donate $100 to charity.

Notes for Rich#

• Option A is the safest for a professional audience — credits Juan and Cassian, explains the problem, shows the scope, invites conversation at the event.
• Option B is better if your LinkedIn audience prefers brevity — punchy stats, clear CTA.
• Option C is the most engaging — the jade bangle story is memorable and it shows vulnerability (we found a gap and fixed it). But it’s longer and more personal.
• All three tag API Days Singapore. Consider tagging Juan Cruz Viotti, Cassian Smith, Jon Scheele (API Days organiser), and Sourcemeta directly.
• The $100 charity challenge in Option C is a bold move at a live event — only use it if you’re confident (which you should be after today’s session).
• Add a photo: the willscan.ai extraction screen showing Katrina’s will turning into a family tree would be powerful.
