We support the proposal to add circular arcs to JSON-FG. Dutch base registry data from the large scale topography dataset (BGT) contains a lot of arcs. We created some small test files containing such arcs and it seems that this costs little effort to support, and satisfies a requirement that is not uncommon.
In order to support adoption and implementation of JSON-FG, it would be helpful to have more basic tooling that supports JSON-FG, such as:
- validators to test if a JSON-FG file conforms to the standard. Not all requirements are covered by the JSON Schema. We are working on a linter in JSON-FG linter, more validators would be useful.
- tooling to read/write JSON-FG. We are working on a JSON-FG encoding and decoding library for Java. More tooling like this would useful.
