You may have some data about books or publications that you curate and
quality check internally and you also make it accessible to others by, for
example, providing a SPARQL endpoint for it or a Linked Data API or
whatever.

Resources in your data have URIs and, as you made these URIs publicly
known, other people could make statements about these URIs that you don't
agree with. They could also take the data you are making available and run
some reasoning over it using OWA.

What problem does this present and what does it have to do with the topic
of this discussion?
