Attaching Media to a Group in the Tree of Life

The Tree of Life project is a collection of materials about the phylogenetic relationships and characteristics of organisms. Within the project's information architecture, things like images, sound files, or text sections are treated as objects that are attached to the groups in the phylogenetic Tree of Life. Data in the ToL database are thus phylogenetically structured, allowing for the management and display of our diverse content within an evolutionary framework.

images attached to groups in the tree

We are asking ToL media contributors to help us maintain this phylogenetic data structure by attaching their images, sounds, and video files to groups in the Tree of Life in the Attached to Group(s) section of the Media Data form:

To allow for optimal data management, you should always attach your contribution to those groups to which it is most relevant, for example:

When you enter the name of an organism in the Scientific Name field, people will find your media file when they search using that name. However, when you attach your media file to a group, it will automatically be associated not only with one particular name but also with any alternative names we have stored for that group. In addition, if the valid name for a group changes, the data for your media file will update automatically through its group attachment, while the entry in the Scientific Name is static and can only be updated manually.

links for media files Group attachments also support phylogenetically structured searches and browsable media collections on the Tree of Life. In the ToL Media Search, you can restrict your search to any named group in the tree, not just to a few presorted taxonomic ranks. You can also browse through all the media files for a given group via the Tree of Life media collections that are linked to each branch and leaf page in the right sidebar. When you attach your media contribution to a group, it is automatically featured in all relevant media collections. For example, a picture of a monarch butterfly that is attached to the group Danaus plexippus, will be featured in the Danaus plexippus image collection, the Danaus image collection, the Danaini image collection, the Danainae image collection, etc., all the way down to the Life on Earth image collection. By default, new contributions are listed at the top in these collections, but you can also have media files shown in random order. People can thus browse through the diversity of organisms at whatever level they are interested in, and they will encounter your media files in many different contexts.

Finding the most appropriate group for attaching your media files may take a little bit of research, but while you search for your organism's place in the hierarchy of life, you can learn something about its relatives, and you will probably come across many other creatures that are well worth exploring.
