Reusable reference skills for LLM tooling. Download a zip and install it as a custom skill in claude.ai, Claude Code, or any compatible tool that supports the Agent Skills format.
Prefer to let your agent handle it? Point it to
manifest.json or
llms.txt and ask it to download and install
the skills you need.
Download all skills in one zip — installs everything at once.

Use when working with bblock.json, schema.yaml, examples.yaml, bblocks-postprocess, or any OGC Building Blocks register.

Covers validating data, resolving bblocks:// refs, semantic uplift, and the bblocks-client-python library. Use when an agent needs to integrate with, validate against, or query an existing OGC Blocks register.

Supports overriding default or generic mappings (e.g. schema.org) with semantically richer, schema-specific ones via an override mapping block. Respects schema import dependencies: never redefines elements inherited from other blocks. Use when adding RDF/vocabulary meaning to a schema written without it, when mapping JSON properties to defined predicates, or when semantic uplift must yield a well-formed, validatable RDF model. Note: publishing the ontology to a Linked Data environment lets these mappings resolve at run-time, including multilingual labels.
