Background and Summary

This is an important Implementation Note on the most efficient way to structure thumbnails on a IIIF canvas. We have seen implementations of the recommendations and if implemented correctly can provide a substantial speed up in the loading of thumbnails particularly for a large Manifest. We would like the TRC to approve this recommendation to encourage viewer developers to implement this recommendation and Manifest producers to start structuring their Manifests and thumbnail infrastructure in the method advocated.

The solutions mentioned in this recipe will only be suitable for institutions which are able to setup their infrastructure in the way recommended so will not preclude the simpler methods mentioned in the basic thumbnail recipe from working.

Voting and changes

We welcome comments on the recipe and as well as voting +1, confused face or -1 feel free to add comments to this issue. If this issue is approved then the author will take account of the comments before we merge the branch in to the master cookbook branch.

If the recipe is rejected by the TRC then we will make the changes requested and resubmit it to a future TRC meeting. If you feel that your comments are substantial enough that the recipe should be looked at again by the TRC after the changes have been made please vote -1 (thumbs down). A confused face is treated as abstaining.

Changes to the recipe will only be made after the TRC voting process has concluded.
