- by Jeff HelmanTo state the obvious, open-source software (“OSS”), also called “free, open-source software” (“FOSS”) is everywhere. (I’ll use “OSS” in the rest of this article for consistency.) OSS packages keep the Internet operating, and nearly every company and government agency uses OSS. Literally every computer user globally relies on OSS to function. This is hard to […]
- by Jeff HelmanAs of early 2025, we have replaced our occasional Touchstone Training sessions with monthly Touchstone Office Hours & Demo sessions (the third Monday of each month @ 1:00 pm ET), during which we engage with the Touchstone community (current users, fans, skeptics, tire-kickers; all are welcome) to: Answer questions about Touchstone, FHIR testing, or you-name-the-topic; […]
- by Jeff HelmanAnyone who has been around software development for a while has confronted the insistence by stakeholders that we conjure up a silver bullet to make all their dreams come true, such as unlimited features on a minimal budget, along with algorithms that make costs and effort magically disappear. (OK, I am exaggerating. Slightly.) got AI? […]
- by Jeff HelmanWith the number and sophistication of HL7® FHIR® Implementation Guides rapidly increasing, knowing that your FHIR implementations are conformant to those IGs and the underlying FHIR specifications is more important than ever. Touchstone is the anchor of our FHIR validation ecosystem which empowers your FHIR implementation team to objectively measure the accuracy of their implementation […]
- by Mario HylandSince our May 2023 Touchstone Release 6.0.0, the AEGIS Health IT team has been preparing the Touchstone community for our updated 2024 subscription pricing model. Touchstone 6.0.0 marks the transition from the introductory pricing accompanying our original R&D effort to a pricing model reflecting a production-hardened, full-featured enterprise-class product offering.

- by Jeff HelmanDuring the past few HL7® quarterly FHIR® Connectathons and Workgroup Meetings, the FHIR community has been debating the impact of what I’m calling “version collisions:” when someone makes a FHIR request for healthcare data expecting that they will receive a response conforming to US Core 3.1.1, but they receive a response with data conforming to […]
- by Joe LamyAt this month’s virtual HL7® FHIR® Connectathon, you can validate the full end-to-end HL7 UDAP workflow, including automated checking of requests and responses and the contents of the JWTs within. HL7 UDAP (https://build.fhir.org/ig/HL7/fhir-udap-security-ig/index.html) is an OAuth-2-based authorization mechanism that is on the draft roadmaps of the national HIEs and TEFCA. Here’s a quick demo: https://youtu.be/pCCnV66sItA […]
- by Jeff HelmanThis is the second installment of our “FHIR Starter” series, which we are writing to help teams filter out the noise and excitement of the burgeoning FHIR community so they can focus on the signal–how to be successful with real-world FHIR implementations. If you missed our first installment, check that out here. In this installment, […]
- by Jeff HelmanAs the HL7® Fast Healthcare Interoperability Resources (FHIR®) community grows, an increasing volume of FHIR information and a ballooning community of self-appointed FHIR experts are bursting onto the scene. This is a welcome sign of the emergence of a robust FHIR ecosystem, and we celebrate that. Health IT is hard; as a technical domain, its […]
