Going over our failed and slow query log last week (another administrative task
that we do so you don’t have to), we noticed that for many of our testers, the
first query attempted fails, as it will be copied from an existing application
PREFIX defaults associated with the repository. That’s no fun.
Since the beginning, Dydra has had a set of common prefixes (such as the
rdf:) applicable to all repositories, but we just
added functionality to set your own prefixes at the account and repository
level. There’s now a ‘Prefixes’ tab on both your profile settings and each
repository’s settings where you can copy and paste them from existing queries.
