Versioning: current status

• Model/API breaking changes can be carried out in minor releases e.g. Bio-Formats 5.2.0
• Consumers (e.g. OMERO 5.3.0-m2) need corresponding breaking changes
• Release lifecycles: OMERO/Bio-Formats

Versioning: proposal

• Move to semantic versioning
• Major version X MUST be incremented if any backwards incompatible changes are introduced to the public API.
• Minor version Y MUST be incremented if new, backwards compatible functionality is introduced to the public API.
• Bio-Formats 5.3.0: API additions only
• OMERO 5.3.0: seamless transition to Bio-Formats 5.x

Integration

• Upcoming use cases
• Glencoe Software: JPEG-XR library
• Heterogenous metadata (MULTIMOT, Wellcome)
• High-performance format containers

Integration: limitations

Monolithic block

Integration: proposal

Components re-architecture

Tiling API: status

• Strong support for reading tiles
• Need for greater transparency, documentation and samples in tiled writers
• Few writers support complete tiling implementation (incl. TIFF)

Tiling API: proposal

• API extension to improve usability of tiled Java writers
• New methods in IFormatWriter to set/read the tile size
• New options to enable/disable tiling by default
• Expanded test coverage, documentation and samples

Options API: proposal

• API to pass options using key/value pairs
• Use cases
• IDR: memoization
• Tile vs non-tile writing
• Reader-level options
• Flexible, give more user control
