// General format info...
|
|
//
|
|
// Version format:
|
|
// <major>.<minor>
|
|
//
|
|
// Major version change mean a significant incompatibility.
|
|
//
|
|
// Minor version changes mean some detail changed and can be handled
|
|
// by it's specific handler seamlessly. Backwards compatible.
|
|
//
|
|
//
|
|
// For more info see:
|
|
// DATA - main data
|
|
// IMAGES - image data
|
|
// MARKED - marks data
|
|
// BOOKMARKS - bookmarks data
|
|
// BOOKMARKS_DATA - bookmarks metadata
|
|
// TAGS - tag data

|
|
// Data format change history:
|
|
// none - Gen1 data format, mostly experimental,
|
|
// - has no explicit version set,
|
|
// - not used for real data.
|
|
// 2.0 - Gen3 data format, still experimental,
|
|
// - completely new and incompatible structure,
|
|
// - use convertDataGen1(..) to convert Gen1 to 2.0
|
|
// - used for my archive, not public,
|
|
// - auto-convert form gen1 on load...
|
|
// 2.1 - Minor update to format spec,
|
|
// - MARKED now maintained sorted, live,
|
|
// - will auto-sort marks on load of 2.0 data and change
|
|
// data version to 2.1, will need a re-save,
|
|
// 2.2 - Minor update to how data is handled and saved
|
|
// - now DATA.current is saved separately in current.json,
|
|
// loading is done from current.json and if not found from
|
|
// data.json.
|
|
// the file is optional.
|
|
// - data, marks, bookmarks, tags are now saved only if updated
|
|
// 2.3 - Minor update to sorting restrictions
|
|
// - now MARKED and BOOKMARKS do not need to be sorted
|
|
// explicitly in json, they are now sorted as a side-effect
|
|
// of being sparse.
|
|
// This negates some restrictions posed in 2.1, including
|
|
// conversion of 2.0 data.
|
|
// NOTE: TAGS gid sets are still compact lists, thus are
|
|
// actively maintained sorted.
|
|
// ...still thinking of whether making them sparse is
|
|
// worth the work...
|
|
// 3.0 - Gen4 DATA format, introduced several backwards incompatible
|
|
// cahnges:
|
|
// - added ribbon GIDs, .ribbons now is a gid indexed object
|
|
// - added .ribbon_order
|
|
// - added base ribbon
|
|
// - ribbons are now sparse in memory but can be compact when
|
|
// serialized.
|
|
// - auto-convert from gen1 (no version) and gen3 (2.*) on load
|
|
//
|
|
//
|
|
// NOTE: Gen1 and Gen3 refer to code generations rather than data format
|
|
// iterations, Gen2 is skipped here as it is a different project
|
|
// (PortableMag) started on the same code base as ImageGrid.Viewer
|
|
// generation 1 and advanced from there, backporting some of the
|
|
// results eventually formed Gen3...
