Hello!
I need to search DbPedia uri by wikipedia link (entered by user). For
example:
SELECT ?uri WHERE
{
?uri foaf:page <http://en.wikipedia.org/wiki/Moon>
}
But I need to make this query case-insensitive (for the case when, for
example, user enters ".../moon" instead of ".../Moon"). Here is what I
tried:
Unfortunately case actually means something in Wikipedia, unlike
Windows, which plays both sides of the road. Last time I checked there
were about 10,000 entries in Wikipedia that differed only by case.
In your case, you might (almost) get the results you want by
searching on the rdfs:label field (which gives the title) but the real
treasure trove of alternate names is under the
dbpedia-owl:wikiPageRedirects field which doesn't (I think) get
materialized as text. Note that these alternate names are often too
embarrassing to display but OK to accept for searching.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
