How to Create Media (Images)

Digital images and associated metadata can be related to records in Arctos through the Media function. When processing large volumes of images, it may be more efficient to use the Media Bulkloader rather than manually enter each media record through the Create Media screen.

Media should be uploaded first to TACC where they are accessible on a web server (see How to Upload Media to TACC)

NAVIGATION: Search Menu → Media → “Create Media” hypertext

Media URI

Enter the Uniform Resource Identifier (URI) that finds the media object on the Internet (a URL is a common type of URI). URIs should be stable in order to avoid broken links - If your files are at TACC, enter the TACC url here. Or, click the “Upload” hypertext next to the URI field to browse and upload the image file directly from your computer. Filesize should not exceed 500K.

Preview URI

Enter the URI for a thumbnail preview of the Media object in this field. If you are in the “Upload” window, browse your computer for a thumbnail file, or leave the Preview URI field blank in order to auto-generate a thumbnail preview of the large format image - If your files are at TACC and processed into thumbnails there, enter the TACC url here. Preview filesize should be well under 10K and scale to ~1200x, previews larger than 48K will NOT be displayed.

MIME Type

Specify the MIME TYPE, which consists of a type and subtype, (e.g., “image/jpeg”). Values are controlled by a code table.

Media Type

Select the kind of media you are creating from the code table (e.g., audio, image, video). The Media Type field exists to categorize media whose MIME type is not sufficiently descriptive (e.g., an HTML image viewer application would have MIME_TYPE of text/html and MEDIA_TYPE of image).

License

Select a value from the code table that describes permissions regarding copyright, use and distribution of related media. Code table includes Creative Commons licenses, institutional policies, and an Arctos Data Ownership and Use Policy.

Media Relationships

Link the media to specimens, agents, projects, accessions, publications, etc. by selecting the relevant Media Relationship from the code table. This action will bring up a search box so that you may query the specific specimen record, agent, project, accession, publication etc. in which the media will display. For example, to link media to a Specimen Record:

Relationship values:

Media Labels

Summarize media through the Media Labels menu (e.g., aspect, subject, made date). Values are controlled by a code table. Note that text entered into the Description label field will be displayed below the image/media object as a title.

Click the “Create Media” button. The image will now be available in the record(s) specified in Media Relationships fields (you may have to refresh the relevant page/wait a few minutes before the media displays).
