  • Fix exception when triples have the Blank Node (in the format of _:)

  • Parser
    • fix bugs in trimming

0.2.2

  • graph.dart
    • fix a bug of parsing and serializing @base and :

0.2.1

  • graph.dart:
    • remove comments before parsing
    • add function to add a triple to groups by passing in subject, predicate and object as strings
    • update prefixes context for 'a' (rdf:type)
    • fix a bug of causing duplicated triples added to the graph

0.2.0

  • grammar_parser.dart: customize evaluators for different parsed result
    • Support every rule specified in the documentation)
    • Will support parsing and ignoring comment # in the future
  • graph.dart: add a new parsing function to utilize new grammar parser
    • Support serializing full form of triples to shorter and simpler forms
    • Will support parsing with file path in the future

0.1.10

  • Use dart petitparser package to rewrite a few of the parsing functions of turtle file base on the rules
  • naive_parser.dart: support parsing for HEX, UCHAR, IRIREF, PN_CHARS_BASE
    • Include test cases for the above rules in test/naive_parser_test.dart
  • grammar_parser.dart: support modular grammar definitions for the above rules

0.1.9

  • term.dart: update isValidUri to static method
  • graph.dart: add support for reading different forms in subject/predicate/object to full URIRef form
    • Case 1: <valid_uri> => URIRef(valid_uri)
    • Case 2: <invalid_uri> => (there should be a default base to interpret this invalid uri) URIRef(base_uri+invalid_uri)
    • Case 3: a:b => URIRef(context[a]+b)
    • Case 4: :a => (there should be a shorthand prefix : in namespace prefix section) URIRef(shorthand_uri+a)

0.1.8

  • graph.dart: add support for parsing and writing @base and @prefix : in namespace prefixes section
  • constants.dart: create constants in this file to be imported to other files if necessary

0.1.7

  • graph.dart: add function in Graph to parse a whole text string in additional to a file.
  • Add a corresponding example for parsing full text string.

0.1.6

  • graph.dart: fix issue of encryption/decryption by using a different key
    • sha256 is for quick verification of hashed passphrase
    • sha512 is for encryption/decryption

0.1.5

  • graph.dart: adding optional decryption for the encrypted ttl file
    • Note the encrypted file must contain a hashed key triple (for quick verification of password) and the encrypted data triple
    • sha256 is used for hashing and verifying the password

0.1.4

  • graph.dart: adding optional encryption when serializing graph data to ttl file.
    • AES is the default encryption
    • sha256 is used for generating hashed passphrase
