14 This contains a list of 62 prefix and URI pairs that are commonly used
15 in RDF. The intention is that prefixes in this list can be safely used
16 in code that has a long lifetime. The list has been derived mostly from
17 W3C standards documents, but also some popularity lists. See the source
18 code of this package for the full list.
19
20 It is intended to be used with e.g. URI::NamespaceMap.
21
22 Methods
23 "new"
24 Constructor. Takes no arguments.
25
26 "uri($prefix)"
27 This will return the URI (as a plain string) of the supplied prefix
28 or "undef" if it is not registered.
29
30 "prefix($uri)"
31 This will return the prefix corresponding to the supplied URI
32 string or "undef" if it is not registered.
33
34 "qname($uri)"
35 This will return the qualified name corresponding to the supplied
36 URI string or "undef" if it is not registered. In scalar context,
37 it will return the prefix and local name with a colon, and list
38 context, a two-element array containing prefix and local name.
39
40 For example "http://purl.org/dc/terms/name" will return "dc:name"
41 in scalar context and "('dc', 'name')" in list context.
42
43 "all"
44 This will return a hashref with all prefix and URI pairs.
