Clean Url (module for Omeka S)

Clean Url is a module for Omeka S that creates clean, readable and search engine optimized URLs like https://example.com/my_item_set/dc:identifier instead of https://example.com/item/internal_code. Used identifiers come from standard Dublin Core metadata, or from a specific field, so they are easy to manage.

This Omeka S module is a rewrite of the Clean Url plugin for Omeka by BibLibre and intends to provide the same features as the original plugin.

Installation

Uncompress files and rename module folder "CleanUrl".

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

Usage

Clean urls are automatically displayed in public theme and they are not used in the admin theme. They are case insensitive.

This module may be used with the module Archive Repertory to set similar paths for real files (item_set_identifier / item_identifier / true_filename).

Identifiers

Simply set an identifier for each record in a field. The recommended field is Dublin Core:Identifier.

• Identifiers can be any strings with any characters, as long as they don’t contain reserved characters like "/" and "%".
• To use numbers as identifier is possible but not recommended. if so, it’s recommended that all records have got an identifier.
• A prefix can be added if you have other metadata in the same field.
• A record can have multiple identifiers. The first one will be used to set the default url. Other ones can be used to set alias.
• If the same identifier is used for multiple records, only the first record can be got. Currently, no check is done when duplicate identifiers are set.
• Reserved words like "item_sets", "items", "medias", sites and simple pages slugs...) should not be used as identifiers, except if there is a part before them (a main path, a item set identifier or a generic word).
• If not set, the identifier will be the default id of the record, except for item sets, where the original path will be used.

Structure of urls

The configuration page let you choose the structure of paths for item sets, items and files.

• A main path can be added , as "archives" or "library": https://example.com/main_path/my_item_set/dc:identifier.
• A generic and persistent part can be added for item sets, items and files, for example https://example.com/my_collections/item_set_identifier, or https://example.com/document/item_identifier.
• Multiple urls can be set, in particular to have a permalink and a search engine optimized link.
• If multiple structures of urls are selected, a default one will be used to set the default url. Other ones can be used to get records.

So the configuration of the module let you choose among these possible paths:

Item sets

- / :identifier_item_set
- / generic_item_set / :identifier_item_set
- / main_path / :identifier_item_set
- / main_path / generic_item_set / :identifier_item_set

Items

- / :identifier_item (currently not available)
- / generic_item / :identifier_item
- / :identifier_item_set / :identifier_item
- / generic_item_set / :identifier_item_set / :identifier_item
- / main_path / :identifier_item
- / main_path / generic_item / :identifier_item
- / main_path / :identifier_item_set / :identifier_item
- / main_path / generic_item_set / :identifier_item_set / :identifier_item

Medias

- / :identifier_file (currently not available)
- / :identifier_item / :identifier_file (currently not available)
- / generic_file / :identifier_file
- / generic_file / :identifier_item / :identifier_file
- / :identifier_item_set / :identifier_file
- / generic_item_set / :identifier_item_set / :identifier_file
- / :identifier_item_set / :identifier_item / :identifier_file
- / generic_item_set / :identifier_item_set / :identifier_item / :identifier_file
- / main_path / :identifier_file
- / main_path / :identifier_item / :identifier_file
- / main_path / generic_file / :identifier_file
- / main_path / generic_file / :identifier_item / :identifier_file
- / main_path / :identifier_item_set / :identifier_file
- / main_path / generic_item_set / :identifier_item_set / :identifier_file
- / main_path / :identifier_item_set / :identifier_item / :identifier_file
- / main_path / generic_item_set / :identifier_item_set / :identifier_item / :identifier_file

Note: only logical combinations of some of these paths are available together!

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.
