Overview
This is a memo about trying prefix.cc for resolving prefixes in RDF data.
prefix.cc
Namespace Lookup API
This is a service that allows you to retrieve URIs by providing a prefix.
prefix.cc
For example, providing the following:
prefix.cc
Returns the following result.
{
"foaf": "http://xmlns.com/foaf/0.1/"
}
Reverse Lookup API
For example, providing the following:
prefix.cc
Returns the same JSON result as above.
Adding New Entries
The following jps prefix used by Japan Search was not available.
{
"jps": "https://jpsearch.go.jp/term/property#"
}
So I tried registering it as a new entry as shown in the screen below.

Afterwards, it could be used like other prefixes.
prefix.cc
It appears that registered entries are evaluated by voting, and you can submit a +/- vote once per day.

References
ex was also registered.
prefix.cc
{
"ex": "http://example.org/"
}
Summary
We hope this is helpful for prefix resolution.
