File Management
File and Media management have seen major changes in ARK2, with a more flexible system implemented.
- Files are now a core Module instead of a dataclass and look-up table, allowing for flexible metadata based on file type, and using files as either data properties or relationships.
- The file system is abstracted using FlySystem allowing files to be transparently saved locally or to cloud providers.
- File versioning is supported.
- Image manipulation is abstracted using Glide and Imagine which supports ImageMagick or GD.
- Thumbnails are stored separately from the master files to make backups, archiving, and regeneration easier
- Multiple thumbnail profiles can be configured
- Thumbnails will be generated asynchronously, so can either be queued for batch processing, delayed until a suitable time window, or only generated when needed.
The Media Types and File Types supported are configurable, with the IANA standard types provided by default:
- Image (jpg, png, etc)
- Audio (mp3, etc)
- Video (mkv, etc)
- Text (txt, etc)
- Application (pdf, odt, ods, etc)
In multi-tenant mode, the files for each ARK instance are stored separately under the 'sites' folder, e.g. 'sites/mysite/files'.
The directory structure for each instance is as follows:
- files
|- download
|- <user>
|- upload
|- <user>
|- tmp
|- <user>
|- data
|- <mediatype>
|- <tokens>
|- cache
|- <profile>
|- <mediatype>
|- <tokens>
where the <mediatype> is as defined in the configuration, and the <token> is a configurable token to split the folders into manageable sizes. By default the <token> will be split by file id in groups of 1000, so subfolders for 0, 1000, 2000, 3000, etc.
The individual file names will be in a standard format. Flysystem abstracts folders and file names as a relative path, which will take the form:
files/data/<mediatype>/<token>/<id>.<revision>.<suffix> files/cache/<profile>/<mediatype>/<token>/<id>.<revision>.<suffix>
There will be no direct file or image links, all files are considered private and requests to the mapped URL will be security checked. The mapped URL forms will be:
files/<id>/<name> files/<id>/<basename>_<profile>.<suffix>
A custom Flysystem manager is provided that allows different filesystems to be transparently mounted at different points in the file path. For example, the root files/ path is mounted locally, but files/data/ is mounted on Amazon S3.
Metadata
Full metadata is supported in line with Dublin Core.
Versions
Design Work
- Data downloads / exports
- Documentation files
- Temp files with expiry
- Mapping files
Very similar to http://documentation.concrete5.org/developers/working-with-files-and-the-file-manager/overview
