1
+ === 0.4.2
2
+ * Released as RdfContext gem
3
+
4
+ === 0.2.2
5
+ * Added AbstractSqlStore and SQLite3Store
6
+ * Store contexts are always graphs
7
+
8
+ === 0.2.1
9
+ * Added MemoryStore, a context-aware store based on Python RDFLib IOMemory
10
+ * Add ConjunctiveGraph, a conjunction of all graphs in a context-aware store
11
+ * Triple(nil, nil, nil) is wildcard, plus variations. No support for regular expressions.
12
+ * BNodes not graph/store specific, generated using milli-second time and sequence.
13
+ * Graph(:store) may be one of :list_store or :memory_store, which will instanciate appropriate store
14
+ * Graph#contains? iterates over triples if object is a literal to allow for fuzzy matching.
15
+ * Change gem name to "gkellogg-reddy" to allow publishing to Github.
16
+ * ConjunctiveGraph tests.
17
+
18
+ === 0.2.0
19
+ * API and RDoc cleanup
20
+ * Removed Graph#each_with_subject, Graph#get_resource, Graph#has_bnode_identifier?
21
+ * Added Graph#predicates and Graph#objects
22
+ * Changed Graph#triples to take optional subject predicate and object to match statements.
23
+ * Renamed Graph#bind o Graph#merge!
24
+ * Graph#triples yields triples if a block is provided
25
+ * Changed Namespace#short to Namespace#prefix
26
+ * Change BNode to require a graph. Most uses go from graph.bnode, rather than BNode.new. This is required because bnodes are only equivalent within the same graph
27
+ * Added identifier to Graph, defaults to BNode. This from Python RDFlib based on TriX recommendation, see: http://www.w3.org/2004/03/trix/
28
+ * Only add triple to graph if it does not already exist in graph.
29
+ * Added Graph#contains? to look for existance of triple.
30
+ * Added Graph#eql? (and ===) to do simple check for graph equality. This version ignores BNodes (like Python RDFlib)
31
+ * Prepend "named" to named BNodes to ensure no overlap between generated and named BNodes.
32
+ * Added Graph#clone and Triple#clone
33
+ * Merge Graphs, replacing BNodes with new values from new graph.
34
+ * Remove duplicate triples when adding or merging graphs
35
+ * Added Abstract Store and List Store.
36
+ * Delegate Graph methods to store. Currently only supports :list.
37
+ * Reduce dependence on HTML namespace in RDFa parser.
38
+ * Add RDFa tests for HTML4 and HTML5
39
+
40
+ === 0.1.5
41

42
+ * All negative RDF/XML parser tests pass.
43
+ * Add RdfContext::Parser, super-class of other parsers and move common code.
44
+ * Change N3Parser to use same new/parse logic as other parsers.
45
+ * Remove debug array by default, and add in calls to tests.
46
+ === 0.1.4
47
+ * Update N3 treetop parser to version 1.4.0 (no digits in parser rule names).
48
+ * Fix N3 literal handling (still has bug with escaped double quote).
49
+ * Handle N3 <#> prefix.
50
+ * Don't output lang for typed literals in n3 format
51
+ * Rewrite of RDF/XML parser based on spec; passes existing tests.
52
+ * Update rdfcore tests based on rdfa test harness.
53
+ * Move Literal string escape/unescape to string_hacks.
54
+ * Fix literal n3_encoded parsing.
55
+ * All positive RDF/XML parser tests pass.
56
+
57
+ === 0.1.3
58

59

61

63

64
+ * Separate approved and unreviewed tests.
65
+ * Allow for soft failure of unreviewed tests by catching Spec::Expectations::ExpectationNotMetError.
66
+ * Integrate rdfa-test-suite and create test cases in the same manner. (Causing SPARQL problems with XMLLiterals)
67

1
+ = RdfContext
2
+
3
+ Context-sensitive RDF Graphs, including a ConjunctiveGraph.
4
+
5
+ A set of compliant RDF parsers:
6
+ * N3-rdf
7
+ * RDF/XML
8
+ * RDFa
9
+
10
+ Multiple datastores may be attached to a Graph, including Memory, List and SQLite3
11
+
12
+ == DESCRIPTION:
13
+
14
+ RdfContext is an RDF library for Ruby.
15
+
16
+ == FEATURES:
17
+ RdfContext parses RDF/XML, RDFa and N3-rdf into a Graph object. It also serializes RDF/XML and N-Triples from the Graph.
18
+
19
+ * Fully compliant RDF/XML parser.
20
+ * Fully compliant XHTML/RDFa 1.0 parser.
21
+ * N3-rdf parser
22
+ * N-Triples and RDF/XML serializer
23
+ * RDFa tests use SPARQL for most tests due to Rasqal limitations. Other tests compare directly against N-triples.
24
+ * Graph serializes into RDF/XML and N-Triples.
25
+ * ConjunctiveGraph, named Graphs and contextual storage modules.
26
+
27
+ RdfContext is based, in part, on Tom Morris' Reddy gem.
28
+
29
+ Install with 'gem install rdf_context'
30
+
31
+ == Usage:
32
+ === Graphs
33
+ Instantiate a graph using Graph.new. A Graph may take an :identifier (defaults to a BNode) and
34
+ a :store (defaults to :list_store)
35
+
36
+ use RdfContext
37
+ g = Graph.new(:store => :list_store, :identifier => URIRef.new("http://example.com"))
38
+ g = Graph.new(:store => SQLite3Store.new(:path => "store.db"),
39
+ :identifier => URIRef.new("http://example.com"))
40
+
41
+ g.add(Triple.new(subject, predicate, object))
42
+
43
+ Graphs also store namespace associations, and can serialize graphs to RDF/XML or N-triples
44
+
45
+ g.bind(Namespace.new("http://example.com", "ex"))
46
+ g.namespace("ex")
47
+ g.prefix("http://example.com")
48
+
49
+ g.to_rdfxml
50
+ g.to_ntriples
51
+
52
+ Instantiate an existing graph from a datastore
53
+
54
+ s = SQLIte3Store.new(:path => "store.db")
55
+ g = Graph.new(:store => s, :identifier => "http://example.com/context")
56
+
57
+ === Parsers
58
+ Instantiate a parser and parse source, specifying type and base-URL
59
+
60
+ use RdfContext
61
+ p = Parser.new
62
+ graph = p.parse(input, "http://example.com", :type => :rdfxml)
63
+
64
+ or, instantiate a type-specific parser:
65
+
66
+ p = RdfaParser.new
67
+ graph = p.parse(input, "http://example.com")
68
+
69
+ or, parse directly into a graph
70
+
71
+ g = Graph.new(:identifier => "http://example.com", :store => :sqlite3_store)
72
+ g.parse(input, "http://example.com", :type => :rdfxml)
73
+
74
+ === Data Stores
75
+ ListStore:: simple non-context aware datastore based on Array
76
+ MemoryStore:: context aware datastore using multiple hashes to optimize triple lookkup
77
+ SQLite3Store:: context aware datastore using a SQLite3 database to create a persistent storage model
78
+
79

+ * Treetop
83

84

86

87
+ === For testing

89
+ * ActiveSupport
90
+
91
+ == INSTALL:
92
+
93

97
+ * Integrate ntriples tests in spec/ntriples/test.nt
