Replace backslashes in URIs

[jindrichmynarz]

Some URLs in the extracted TED dataset that are reused from the source XML data contain backslash characters (i.e. \), which are not allowed to be a part of URI unescaped. For example, backslashes appear in URL values of pc:buyerProfile (BTW, this should be changed to pc:profile). In most cases, this is a typo of replacing the regular forward slash with the backslash.

The solution to this issue could be to replace any backslashes in source URLs by forward slashes. A more conservative option would be to escape the backslashes.

In fact, it would be better to just escape the backslash or treat the whole value as literal instead of a URI, because there are values such as www\lovech.bg, where the straight-forward replacement with forward slash cannot be applied.

Contracs has a value of pc:buyerProfile formatted as literal for now. About older Contracts I suggest change URIs to literals using SPARQL UPDATE query. May I do it?

OK. Please update the older data tomorrow or later (the lod2.vse.cz server should be kept highly available due to the LOD2 review).
