The FOLIO Project is moving quickly in several independent development streams to build functionality on the platform. For information on the development plans, please consult these two documents:
FOLIO Development and Milestone Plan (v1 document)
This Excel spreadsheet shows the high-level timing and coordination of platform apps under development for the version-1 release in 2018. The document is maintained by Hkaplanian in consultation with the FOLIO Product Council and the software development teams.
This Google Spreadsheets document has a finer granularity of description of functionality in development or under consideration by the special interest groups. The document is maintained by members of the various special interest groups (SIGs). Rows with a "1" in the second column of each sheet are prioritized for version-1 development (also known as "above-the-line" functionality).
