rdflib 0.1.6

A pure Dart package for working with RDF (resource description framework).

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
  • AES is the only supported decryption now (depends on encrypt)

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
  • new encrypted file will still be a valid ttl file with original contents encrypted in one triple

0.1.3

Adding acknowledgement for RDFLib

Adding examples for reading and writing a full ttl file, check it out in the example/ folder!

• graph.dart:
  • fixing bugs in reading lines ending with ., , and ;
  • [partly] fixing prefix lines starting with ':' and '@base'
  • fixing bugs in reading single numeric values (with no specified datatypes)

0.1.2

Updating description and GitHub repository.

0.1.1

Renaming rdfgraph to rdflib. (GitHub repository stays the same)

0.1.0

• graph.dart: supporting reading local turtle file into a Graph instance in memory
• updating example/rdfgraph_example3.dart to demonstrate parsing local ttl file

0.0.11

• graph.dart: adding function addObjectProperty() to link two named triple individuals together
• updating example/rdfgraph_example2.dart to demonstrate linking triples

0.0.10

• term.dart: Literal default constructor can parse integer, float/double, and date time strings with corresponding XSD types
• graph.dart: adding named individual
• Adding derived SOLID Health Ontology Example examples for demonstration
• Updating README.md to include new examples

0.0.9

Updating pub.dev page sidebar homepage link to new ANUSII GitHub repository.

0.0.8

• namespace.dart: adding default namespaces (e.g., RDF, RDFS, OWL, and XSD ) with reserved vocabulary of OWL 2 including special treatment, refer to this link for more details
• triple.dart: converting single string value in object to a Literal instance with datatype xsd:string
• term.dart:
  • refactoring constructor to accept full URI
  • updating base address later if need be
  • adding Literal class with data type and language options for more specific object description
• graph.dart:
  • updating contexts when adding triples with different types
  • serializing prefixes based on contexts

0.0.7

Improve serialize() by shortening full URIRef instance to the bound namespace name.

0.0.6

Update Graph class:

• add bind() method to bind string to a namespace for code readability
• add serialize() method to export the graph to turtle format file.

Update documentation based on dart guide here

0.0.5

Move example code to the top example/ folder.

0.0.4

Add methods to find subjects and objects based on the criteria in the graph.

Update package description with what it can do currently.

Add example file in example/ folder.

Tidy up unused imports.

0.0.3

Add examples, refer to README.

• Namespace
  • add RDF and FOAF (incomplete lists)
• URIRef
  • add comments
  • update methods
• Triple
  • update method

0.0.2

Add the following simple naive classes:

• Graph
• Namespace
• URIRef
• Triple

Functionalities in creating the graph:

• add triple to the graph
  • this will not add duplicates because a set structure is used to store the triples

0.0.1

Take baby steps in creating RDFGraph package.
