Archive Repertory (module for Omeka S)

New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.

Build Status

Archive Repertory is a module for Omeka S that allows Omeka to keep the original names of imported files and to put them into a simple and hierarchical structure consisting of: "item set / item / files", in order to get readable urls for files and to avoid an overloading of the file server.

This module is compatible with Amazon buckets via the module Amazon S3.

Notes

If a duplicate name is detected, an index is added to the filename as a suffix. Check is done on the basename, without extension, to avoid issues with derivative files.

Duplicate names of collections and items don’t create issues, because each file is managed individually. Nevertheless, to use identical names is not recommended, because files of different items or collections will be mixed in the same folder.

Currently, when a collection is moved, files are not moved until each item is updated. The files are still available. This avoids a long process. To update each folder, it’s possible to batch edit items without any operation, so a job will be launched and files will be moved automatically.

This module can be used with Clean Url for an improved user experience and for a better search engine optimization.

Installation

Uncompress files and rename module folder "ArchiveRepertory".

Then install it like any other Omeka module and follow the config instructions.

Tiles for big images created with the module IIIF Server are compatible with this module. To enable it, just open and submit the config page of the IIIF Server, the integration between the two modules will be registered automatically.

Unicode filenames

As Omeka S, the module works fine with filenames with Unicode characters, but all the system, database, filesystem and php web/cli environment on the server should be set according to this format.

An autocheck is done in the config page. You can check it too when you upload a file with a Unicode name.

If derivative files with non Ascii names are not created, check the behavior of the php function "escapeshellarg()", largely used in Omeka. The problem occurs only when Omeka uses command line interface, in particular to create derivative images or to get mime type from files. After, you have five possibilities:

  • use only folder and file names with standard Ascii characters;
  • set options to auto convert files and folders names to Ascii;
  • change the configuration of the server if you have access to it To change an Apache server configuration, simply update config in the file "/etc/apache2/envvars", either:
    • uncomment the line . /etc/default/locale in order to use the system default locale, and add this just below to avoid numerical issues: export LC_NUMERIC=C.
    • or replace "export LANG=C" by "export LANG="C.UTF-8".
  • add this in the beginning the "bootstrap.php" of Omeka (with your locale): setlocale(LC_CTYPE, 'fr_FR.UTF-8'); setlocale(LC_COLLATE, 'fr_FR.UTF-8'); Avoid setlocale(LC_ALL, 'fr_FR.UTF-8'), and keep numerical values as "C": setlocale(LC_NUMERIC, 'C'); Else, you can use a more generic solution: setlocale(LC_ALL, 'C.UTF-8');
  • replace every escapeshellarg() with \ArchiveRepertory\Helpers::escapeshellarg_special()and everybasename()with\ArchiveRepertory\Helpers::basename_special()`.

For more explanation, try the test file.

Warning

Use it at your own risk.

It’s always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.

Troubleshooting
