Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog.

0.96 - 2024-08-08

Added

  • Auto-generated Markdown files using Frictionless (resolves #64)
  • Adds empty template SQLite databases (one using integer and the other using string IDs) to hold a network formatted in accordance with GMNS. This is an optional convenience for users who may wish to exchange GMNS-formatted networks via databases rather than .csv files.
    • Also adds SQL create statements used to create these. The database and create statements are placed in usage/database
  • Documentation website (where you're hopefully reading this now!) at https://zephyr-data-specs.github.io/GMNS/

Changed

  • The automated generation of markdown has resulted in several non-substantive changes to the markdown files, as well as a change in their appearance:
    • Their names are in lower case (e.g., node.md) rather than mixed case (e.g., Node.id)
    • Datatypes for the ID fields are "any", carried straight from the json files
    • Datatypes are number (rather than numeric), string (rather than text)

Note that In the json schema files, the ID fields (node_id, link_id, etc.) has always been defined as type "any", allowing text or integer to be used. This follows the example of unique_ID as defined in GTFS. It is certainly possible that an application may further restrict ID fields to be integer (issue #83).

0.95 - 2024-06-14

Added

  • Add expanded example network (Cambridge, MA)

0.94 - 2023-06-15

Added

  • Config information is now stored as a new config table at the dataset level (fixes #59)
  • New curb_seg table to provide a separate segment object for curbside regulations, which may change at different locations (and more frequently) than segment-level changes to the travel lanes
  • Addition of zone tables to two examples (fixed #56)

Changed

  • Adjustments to the signal phasing tables to fix #57
  • Standardized bike_facility type names to fix #58
  • Updates to validation code to use Zephyr-hosted repo (GMNSpy#2)
  • Minor updates to reflect spec changes above
