Using Archipelago's 'Webform LoD from CSV attached to an ADO suggest'

Archipelago's custom webform element 'Webform LoD from CSV attached to an ADO suggest' provides a form element autocomplete labels/urls(values) from a CSV attached to a Digital Object. Using this element affords a way for you to utilize a custom local vocabulary, a subset of labels and URIs from a wider LoD authority source, or an LoD vocabulary that does not have an accessible API or public query service.

To use this element, you need to first have prepared a CSV file containing two columns only:

  • one column for 'label' containing the labels for your vocabulary
  • one column for 'uris' containing the corresponding uris for your vocabulary

2. New ADO Using Your CSV File

Create a new Digital Object, and attached the prepared CSV file to the new Digital Object.

  • Be sure to provide a unique label to help you identify this Object in future steps.
  • It is recommended that you do not Publish this Object.
