<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">First of all, thank you Jana for summarizing our discussion. The text reflects all the problems and arguments, I think.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">After reading about our discussion, I once again thought about my idea to apply a checksum within the document, which then can be verified via an https connection. But at second thought, I see that
the idea was not well thought out. There are various problems with this approach. To mention only one: If anybody adds a checksum to a document, then the checksum of the document changes, thus the provided checksum is invalid.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Anyhow, I stumbled upon the Linked Data Signatures draft [1], which yields the same problem but with a superior technology (public/private keys etc.).

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">I don’t think, that this is really an option for library data providers: Too hard to implement, too much data overflow. But anyhow, I just wanted to let you know.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">We had this enlightening Breakout Session during SWIB18 together and I promised to wrap it up and store the results in the Wikispace of the German Competence
