| The LinkML meta-model and the LinkML runtime are back in sync. Both are at version 1.10.0 right now, but we are aiming for a quick release of 1.11.0 in mid April. |
|
| |
|
| LinkML v1.10.0 (Release Notes) --- Highlights: Squashed bugs and improved adherence to metamodel elements in Pydantic, SHACL, OWL, Java, GoLang, CSV/TSV and ER Diagram generators. New: Data Dictionary generator — document your schema as a single readable Markdown file, perfect for sharing with collaborators who don't use LinkML directly. |
|
LinkML Project Copier v0.4.2 (Release Notes) --- Highlights: New home in the LinkML organization. New projects should default to this to start new LinkML schema projects (for an overview see community meeting reports below). |
|
| |
|
| LinkML-Map v0.4.0 (Release Notes) --- Highlights: Enabled cross-table lookup/joins and multi-output stream writers in addition to various ergonomic improvements. |
|
| |
|
| LinkML Term Validator v0.3.0 (Release Notes) --- Highlights: Validates that enums (static and dynamic, e.g. from ontologies) are used correctly in your LinkML-constrained data. |
|
| |
|
| LinkML Java v0.1.2 (Release Notes) --- Highlights: An implementation of LinkML for the Java language (for an overview see community meeting reports below). |
