+    longDescription: >
+      publiccode-parser-go is a Go library and command-line tool for parsing and
+      validating publiccode.yml files against the official standard.
+      It performs syntactic and semantic validation, and verifies the existence
+      of URLs. The library can be embedded in Go applications or used as a
+      standalone CLI validator that outputs errors in JSON or
+      errorformat-compatible format, making it easy to integrate into editors
+      and CI pipelines.
+    features:
+      - "URL existence verification"
+      - "JSON and errorformat-compatible error output"
