Serd 0.28.0 has been released. Serd is a lightweight C library for RDF syntax which supports reading and writing [Turtle][], [TriG][], [NTriples][], and [NQuads][]. Serd is suitable for performance-critical or resource-limited applications, such as serialising very large data sets or embedded systems.

Changes:

• Add serd_node_from_substring()
• Add support for reading from a user provided callback
• Fix hangs when reading corrupt UTF-8
• Fix parsing of hex escapes in file URIs (thanks Johannes Mueller)
• Fix strict parsing of abolute URI schemes
• Gracefully handle applications that write corrupt UTF-8

Serd 0.26.0 has been released. Serd is a lightweight C library for RDF syntax which supports reading and writing [Turtle][], [TriG][], [NTriples][], and [NQuads][]. Serd is suitable for performance-critical or resource-limited applications, such as serialising very large data sets or embedded systems.

Changes:

• Add support for TriG and NQuads
• Add support for braindead SPARQL PREFIX and BASE directives

Sratom 0.6.0 has been released. Sratom is a small library for serialising LV2 atoms to and from RDF, for converting between binary and text or storing in a model. For more information, see http://drobilla.net/software/sratom.

Changes:

• Add sratom_set_env() for setting prefixes
• Fix padding of constructed vectors (thanks Hanspeter Portner)
• Fix warnings when building with ISO C++ compilers
• Support round-trip serialisation of relative paths
• Support sequences with beat time stamps
• Upgrade to waf 1.8.14

Sord 0.16.0 has been released. Sord is a lightweight C library for storing RDF statements in memory. For more information, see http://drobilla.net/software/sord.

Changes:

• Add sord_node_get_string_measured() to get both byte and character counts
• Fix construction and comparison of URIs with UTF-8 characters
• Fix documentation generation
• Make sord_node_get_counted return byte count, and clarify documentation
• Return error from sord_inserter_write_statement() if a node can not be written (e.g. undefined prefix)
• Safely return NULL from sord_iter_get() for end iterators
• sord_validate: Do proper numeric comparison for propery bounds checking
• sord_validate: Tolerate xsd:decimal literals for double and float properties if literals match pattern

Serd 0.24.0 has been released. Serd is a lightweight C library for RDF syntax which supports reading and writing [Turtle][], [TriG][], [NTriples][], and [NQuads][]. Serd is suitable for performance-critical or resource-limited applications, such as serialising very large data sets or embedded systems.

Changes:

• Add serd_node_new_relative_uri()
• Fix construction and comparison of URIs with UTF-8 characters
• Fix documentation generation
• Fix potential out of bounds read
• Fix unaligned memory access, undefined behaviour which breaks on ARM
• Report I/O errors with message and return appropriate status code
• Report missing statement separator errors
• Update serdi man page

Sord 0.14.0 has been released. Sord is a lightweight C library for storing RDF statements in memory. For more information, see http://drobilla.net/software/sord.

Changes:

• Add sord_erase() for erasing statements via an iterator
• Fix bugs with stores that contain both graphs and default graph statements
• Fix compilation on compilers that do not support -pthread flag
• Fix crash caused by multiple deletion of datatype nodes
• Fix minor memory leak in sordi
• Fix using sordi with stdin
• Improve test coverage
• Reduce memory usage and increase performance with a better data structure
• Show sordi errors in standard format
• This release does not break the ABI, but the semantics of iterators has changed: any modification to a model invalidates iterators on that model
• Upgrade to waf 1.8.14
• sord_validate: More extensive validation, including cardinality, PlainLiteral, and someValuesFrom restrictions.

Serd 0.22.0 has been released. Serd is a lightweight C library for RDF syntax which supports reading and writing [Turtle][], [TriG][], [NTriples][], and [NQuads][]. Serd is suitable for performance-critical or resource-limited applications, such as serialising very large data sets or embedded systems.

Changes:

• Add serd_reader_set_strict() and -l (lax) option to serdi to tolerate parsing URIs with escaped characters
• Add support for Turtle named inline nodes extension
• Fix clash resolution when a blank node ID prefix is set
• Fix reading statements ending with a blank then dot with no space
• Fix serd_reader_read_file() for URIs with escaped characters (spaces)
• Fix serializing fractional decimals that would round up
• Fix warnings when building with ISO C++ compilers
• Remove dependence on fmax() to avoid portability issues
• Report errors for invalid IRI characters and missing terminators
• Show serdi errors in standard format
• Upgrade to waf 1.8.14

Sratom 0.4.6 has been released. Sratom is a small library for serialising LV2 atoms to and from RDF, for converting between binary and text or storing in a model. For more information, see http://drobilla.net/software/sratom.

Changes:

• Don't set eg prefix in sratom_to_turtle
• Update for latest LV2 Atom Object simplification
