This screen contains general information about the media file, i.e.:

  • Resource ID

    The IMDI Editor automatically assigns a unique resource identifier to each media file. This assignment is automatic, and cannot be influenced by the user (see Section 2.5).

  • Resource Link

    The link to the corresponding media file, i.e., its name and location.


    Note for researchers working at the MPI for Psycholinguistics, Nijmegen: Please specify only the name of the file – do not make use of the open folder icon to the right of the Link field. The name of the media file should be the same as the name of the IMDI file (see Section, and as the name entered in the field Session Name (see Section 2.1.1). Furthermore, the file name has to be Unix compatible: do not use file names longer than 14 characters, do not use non-letter or non-number characters (except for the underscore: _), and do not use blank spaces.

  • Size

    The (approximate) size of the media file in bytes. Note that this field is not standardized: it is meant to be read by humans (to give them an indication of the size before they, e.g., download it), not to be processed through the computer.

  • Type

    The type of the media file. Choose a value from the pull-down menu, or type in an alternative value.

  • Format

    The format of the media file. Choose a value from the pull-down menu, or type in an alternative value.

  • Quality

    The quality of the recording. Choose an option from the pull-down menu (1 stands for low and 5 for high quality).

  • Recording Conditions

    The technical conditions under which the media file was recorded, e.g., the equipment used in the recording (e.g., microphone type, amplifier type, mono/stereo recording, etc.). There are no constraints on this field. Time Position

The start/end position of the session on the media file. Please enter the start/end position in the following format: hh:mm:ss:f (i.e., hours:minutes:seconds:frames). Access

Information about the access rights to the media file. See Section A.3 for instructions on how to fill in an Access schema. Keys

Keywords that are relevant to the media file. See Section A.2 for instructions on how to fill in a Keys schema. Descriptions

A description of the media file. See Section A.1 for instructions on how to fill in a Descriptions schema. Remember: The field Language refers to the language in which the description is written - not to the language under investigation.
