Metafacture Core Distribution 1.2.2

This is a bug fix release for the 1.2.x branch of metafacture-core.

Bug fixes

• Fixed #178: Reset conditions if sameEntity is true

If a collector has an sameEntity="true" set, it is reset whenever
the current entity changes. As described in issue #178 the current
implementation fails to reset the condition during these reset
operations. This commit fixes this.

Additionally, the test cases for the if-condition have been moved
into a separate xml-file as quite a number of tests have
accumulated so that it makes sense to keep them in a separate file.

Metafacture Core Distribution 1.2.1

This is a bug fix release for the 1.2.x branch of metafacture-core.

Bug fixes

• Fixed #177: Condition was not reset when collector was reset
  If a collector has an reset="true" attribute one would expect that this
  also resets the state of an if-condition in the collector. However, this
  was not the case. This commits fixes this.

  Please note that this may change the behaviour of existing scripts if
  they relied on the condition not being reset with the reset of the
  collector.

Metafacture Runner Distribution 2.0.0

This is the initial release of metafacture-runner. The 2.0.0 version number was chosen to keep it the versioning scheme in sync with the metafacture-core package.

Please see the release notes of the metafacture-core package for changes of the code which is now in metafacture-runner but was part of metafacture-core before.

Metafacture Core 2.0.0

This release is not compatible with the 1.x.x line of metafacture-core.

Incompatible changes

• Removed flux executable and runtime dependencies slf4j-log4j and mysql jdbc
  driver from metafacture-core. The flux command line application is now
  maintained in the culturegraph/metafacture-runner package (see issues #131,
  #130 and #168 and commits 41329a7 and ecdafbc).
• Removed eclipse project files from repository (see commit 27c2390)
• Reimplemented PicaDecoder: The records are now properly parsed. The new
  implementation does not do special processing of subfield "S" like the old
  class did. Additionally, multi-line pica records are supported (see issues
  #51, #109, #112, #137 and #139 and commits 3c75b41, 9e736df, 4483e5e, 89119a6,
  ae5a08a, c0eeb04, ec81279, bd30086, 5c8002e)
• Renamed the configure method in SimpleXmlWriter (now SimplXmlEncoder)
  into setNamespaces to reflect what its actually doing (see issue #99)
• Renamed org.culturegraph.mf.stream.sink.SimpleXmlWriter to
  org.culturegraph.mf.stream.converter.xml.SimpleXmlEncoder (see issue #100)
• The receiver interfaces do no longer extend LifeCycle directly but extend an
  intermediate Receiver interface (see commit 7065cc0)

New features & improvements

• Updated dependencies to latest version (see commit 3ab7331)
• Modified IdChangePipe to accept nested literals as ids (see commit e81b230)
• Modified the Counter module to allow pipe lining (see commit 43c52c3)
• Added pretty printing and configurable character escapes to the JsonEncoder
  (see commit 8cb7a08)
• Added a dateformat function to Metamorph for converting various date formats
  (see commit 6b9b7e1)
• Added a Metamorph function for generating timestamps (see commit 82be110)
• Added triple-to-stream module which converts triples into a stream (without
  collecting them into records as collect-triples does (see commit 55fc144)
• Improvements to LineSplitter: Added flux-annotations to LineSplitter and
  added it to flux commands. (see commit 34aed80)
• Added StreamExceptionCatcher module which is the stream counterpart of
  ObjectExceptionCatcher(see commit 59ff596)

Bug fixes

• Generate Flux parser and lexer as part of the build cycle (see commit a7b4d78)
• The flux lexer was failing on files which had an empty comment not followed by
  a new line as their last line (see issue #147)
• Place OreAggregationAdder and its test in same package (see issue #60)
• Adds the ability to escape the @-character in Metamorph names (see commit
  0b470e5)
• Replaced binary or with boolean or in StreamLiteralFormatter (see commit
  bbe340c)
• Added fallbacks to flux.sh in case realpath is not available (see commit
  b1e1172)
• Moved the logic for creating a buffer to allow direct access to the characters
  in a string into the StringUtil class. The code was fixed to always create a
  buffer that is large enough (see issue #161)
• AbstractTripleSort threw NullPointerExceptions if it received a
  "memoryLow" message before the first record was processed (see issue #160)

Metafacture Core Distribution 1.2.0

The new release should be fully compatible with release 1.1.0. It contains the following new features and bug fixes:

New features

• Added header, footer and separator settings to ObjectWriter (see issue #154)
• New Collector EqualsFilter (see issue #149)
• Set namespace for rdf output via remote configuration in the same way as Metamorph scripts are set (see issue #145)
• Added RecordReader for reading records from a reader. This module is available as as-records in Flux (see issues #140, #142 )
• Add a wrapper for WildcardTrie enabling simple character classes in source statements in Metamorph (see issues #135, #143)

Experimental feature

• Added support for conditional activation of collectors. Additionally a set of quantifiers collectors allows to express Boolean conditions in nice and easily comprehendable way (see issues #151, #154)

Bug fixes

• Changed JsonEncoder to not prefix output with spaces (see issue #152)
• Partially reverted commit 23c05cf: This commit broke the plugin loading mechanism. This should be fixed again (see issue #148)
• Bugfix for RdfMacroPipe: Empty name parameter in literal(..)-method resulted in an StringIndexOutOfBoundsException. The parameter is checked with org.apache.commons.lang.StringUtils now and so the use of empty name parameter is possible again (see issues #146, #150 )
• Fix wrong namespace (dcterm->dcterms) (see issue #136)
