As part of the OASIS retirement, Harvard will no longer support a locally developed EAD schema. As of July 2018, we will be validating against the Library of Congress EAD schema. In order to make the transition, we need to make changes to our finding aids. Please note: In June 2020 the Library of Congress changed their website URL from http to https. Earlier versions of finding aids will have the old LC EAD schema link and this link will need to be update in order for finding aids to open automatically.
Here are the steps to follow:
...
<ead xmlns="urn:isbn:1-931666-22-9" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:isbn:1-931666-22-9 httphttps://www.loc.gov/ead/ead.xsd">

5. Save your document
6. Open the document in XMetaL to make sure the document is still valid. If the finding aid won’t open or is invalid, ask Paula or Johanna for help
