eXact LCMS allows to set which metadata is necessary to describe a content; the metadata configuration has an impact on all the fields that are based on metadata, such as:
|•||The metadata editing environment|
|•||The pages that displays the metadata related to a content|
|•||The search criteria used by the search engine to find material within the repository|
With the system configuration, it is possible to define for each type of content which metadata profile needs to be used by the authors defining:
|•||Which metadata fields are mandatory for the specific context|
|•||How each metadata is identified in natural language|
|•||How the information needs to be associated in accordance with IMS 1.2 or IEEE LOM standard|
Basically, for each "type" of metadata it is possible to define:
|•||A label that identifies that specific metadata, according to the terminological dictionary shared within the company|
|•||A vocabulary of the accepted (or recommended) values used to fill in that specific metadata field|
|•||The minimum number suggested and the maximum required/allowed to fill in such metadata field|
|•||The default value that will be typically used in most cases for such metadata|
|•||The languages that should be used to insert the metadata for the different types of contents present in the repository|
The metadata profile, like any other content, is managed in the repository and is assigned to the different types of content set in the platform, via manual configuration.
When selecting "Metadata", the following window displays:
The following options are available:
|•||Show all metadata|
On the right hand side of the window, a selection of which metadata language to display is also available:
When "Best Language" is selected, the user preferred language will be displayed, if available, otherwise the system will use the first available language.
Show all metadata
When this option is selected, a new window appears showing all the metadata that have been typed in.
To modify metadata select this option. A window showing all metadata will then display.
Within the Content Packaging, the course metadata are grouped in different categories, as follows:
|•||Asset Metadata (assigned to the resources)|
|•||Sharable Content Object Metadata (assigned to the Learning Objects)|
|•||Content Aggregation Metadata (assigned to the course)|
In the dialog window, select the desired metadata field and insert the required value (these fields refer to IMS Metadata subject matter, grouped by categories such as General, Technical etc. ).
On the right hand side of each text field the following icons are visible:
|•||"Other language's values" icon : to add values in different languages.|
|•||and icons: to either add or delete more instances of the same field. These icons are always available; when the maximum number of instances is reached for one element, a warning message is displayed.|
IMS standardised more than 100 hierarchical fields. Some of these fields are free to edit such as "Title", some others may be limited by standard predefined vocabularies, such as "Format".
Make all the requested amendments and press "Save" to save them. To close this window without saving, press "Cancel".
Different types of Metadata are also available:
|•||Vocabulary Lists and Trees|
By selecting this option, the system will check all the metadata present in the selected content and in the window that appears it is possible to view whether some data is missing or it contains not conforming values:
By clicking on it is possible to view the non conformances details:
In case some values are missing from a complex metadata field (such as the date in the author and date field) or if the metadata values are not displayed in one or more languages required by the profile, by selecting the "Edit" link at the bottom of the window, it is possible to add them. In case of some not conforming metedata (for example, if the instance contains some fields which are not required by the profile or if a filed contains a value which does not belong to the vocabulary required by the field), by selecting the "Trim" link, it is possible to eliminate them.
Once all the requested amendments have been made, by selecting "Check" a window similar to the following will display:
