The DLCS provides a powerful platform for building feature rich applications, saving time and money. We have already built a number of applications which can be adapted for your projects:

  • A Crowdsourcing Platform that lets you build your own projects from any source IIIF material, define the information you want your users to capture from that material, and save the results as W3C annotations.
  • A browser-based Sorting Room application that works with any IIIF material and allows users to break it down into smaller pieces, saving the results to our IIIF Presentation API management services.
  • An application to manage simple taxonomies that emerge from a crowdsourcing project, especially when some or all of the terms have come from OCR and entity recognition.
