- rdf_graph_property(?Graph, ?Property) is nondet
- True when Property is a property of Graph. Defined properties
are:
- hash(Hash)
- Hash is the (MD5-)hash for the content of Graph.
- modified(Boolean)
- True if the graph is modified since it was loaded or
rdf_set_graph/2 was called with
modified(false). - source(Source)
- The graph is loaded from the Source (a URL)
- source_last_modified(?Time)
- Time is the last-modified timestamp of Source at the moment that the graph was loaded from Source.
- triples(Count)
- True when Count is the number of triples in Graph.
Additional graph properties can be added by defining rules for the multifile predicate property_of_graph/2. Currently, the following extensions are defined:
library(semweb/rdf_persistency)- persistent(Boolean)
- Boolean is
trueif the graph is persistent.
