imeji offers two different searches:
Select what you want to search (items, collections, or albums) and enter you query. imeji will search for:
- any metadata value
- Filenames
_Note: At present, advanced search is working only for items. _ To use the advanced search, first select a metadata profile. Now you can:
- Select a metadata and enter a search value
- Add new metadata with search values and combine them with boolean operator ([more details](https://github.com/imeji-community/imeji/wiki/Features: search))
- Restrict the search to one specific collection
- Select what file types you are looking for
imeji items are organized within a collection. All items of the collection share the same metadata profile. A collection itself has some descriptive metadata, such as title, description, authors or some additional information. freely defined by the user. Actions you can perform on a collection:
- Create/edit collection (title, description,logo, contributors, download notification)
- Assign a metadata profile to a collection (see Create Own Metadata Profiles or Reuse Existing Metadata Profiles)
- Delete/release/discard collection
Released collections can be assigned with a Digital Object Identifier (DOI) to improve linking and citing of data for scholarly communication. You may add an already existing DOI or use the imeji software to register a new DOI. To use the internal DOI assignment, the imeji configuration needs to point to a DOxI instance which connects to the DataCite Metadata Storage. During the DOI assignment the collection metadata will be registered with the DataCite service and made available for global search. DOxI is implemented as open source software and can be deployed for own usage, sources are available at GitHub.
Definition: An album can contain items from different collections to group them together. These items do not need to have the same metadata. An album has exactly one creator, but can have multiple editors (people who are allowed to edit this album). Actions you can perform on an album:
- Create/edit album(title, description , logo, contributors)
- Edit the metadata of an album
- Adding items to an album via selecting an album as 'active' album when browsing through the items
- Remove items from an album
- Delete/release/discard album
Definition: A metadata profile always belongs to a collection. The user either can create a new metadata profile for a new collection or use an already existing one as template. The metadata profile will define which metadata one can enter for the items of this collection. Each metadata statement consists of:
- A type (a list with several types will be provided, e.g. date, geonames, string, integer, cone-person)
- One or several labels
- A language tag for each label
- a menu to select cardinality (unique, multiple) and preview option
- the possibility to define a small controlled vocabulary based on free text fields (strings)
- the possibility to integrate larger controlled vocabularies from external sources All metadata statements can be arranged hierarchical and the order of metadata statements can easily be changed with drag&drop.
You don't have to create a metadata profile from scratch. Simply reuse the ones available. imeji offers 2 mechanisms:
- Reference a profile: This profile is maintained by another user, you just reuse it as it is.
- Copy a profile: This profile is now yours. You can modify it as you wish. Whatever you do, the original profile won't be affected (and vice versa)
There are several ways to enter/edit the metadata of items.
- Batch edit
- Selective edit
- Single editing
- via RESTful API
To share data with other user (or with user groups), imeji offers 3 mechanisms:
- Share Collection
