0.3.0 (released 2015-02-18)¶
This release adds support for processing things in parallel, both by using multiple processes on a single machine, and also by running “build clients” on any number of machines, which run jobs managed by a central queue.
- DocumentRepository and all derived classes now takes an optional first config argument. If present, this should be a LayeredConfig object that contains the repo configuration. If not provided, a blank LayeredConfig object is created. All other optional keyword arguments are then added to the config object. If you have overridden __init__ for your docrepo, you’ll need to make sure to handle this first argument.
- The Newscriteria class has been removed, and DocumentRepository.news_criteria with it. The Facet framework is now used to define news feeds (as well as TOC pages, the ReST API and fulltext indexing)
- The PDFReader constructor now takes, as first argument, a list of pdfreader.Page objects. Normally, a client won’t have these but must instead provide a filename of a PDF file through the filename argument (which used to be the first argument, but must now be specified as a named argument).
- the getfont() method of pdfreader.Textbox objects used to return a straight dict of strings, but has now been replaced with a font property that is now a LayeredConfig object with proper typing. Code like “int(textbox.getfont()[‘size’])” should now be written like “textbox.font.size”.
- The default serialization of Element objects to XHTML now inserts appropriate dcterms:isPartOf statements when one element with a URI is contained within another element with another URI. Custom element classes can change this by changing the partrelation property of the included document.
- Serialization of Element documents to XHTML now omits namespaces defined in self.namespaces, but which never actually occur in the data.
- CitationParser.parse_string and .parse_recursive now has an optional predicate argument that determines the RDF predicate between the refering and the referred resources (by default, this is dcterms:references)
- manager (and by extension ./ferenda-build.py) has new commands that allows processing jobs in parallell (see Advanced > Parallel processing)
- The ferenda.sources.general.wiki can now transform mediawiki markup to Element objects.
- The ferenda.sources.general.keyword can be used to build keyboard hubs from all concepts that your documents point to through a dcterms:subject property (as well as things in a wiki docrepo, and configurable other sources).
- The ferenda.sources.legal.se docrepos have been updated generally and are now close to being able to replicate the function set of https://lagen.nu/ (which was the main motivation with this codebase all along).
- ferenda.testutil.assertEqualXML now has a tidy_xhtml argument which runs the XML documents to be compared through HTML tidy (in XML mode) in order to produce easier-to-read diffs.
- Transformer now outputs the equivalent xsltproc command if the environment variable FERENDA_TRANSFORMDEBUG is set.
- The relate() action now uses dependency management to avoid costly re-indexing if no changes have been made to a document.
- TOC and newsfeed generation now uses dependency management to avoid re-generating if no changes in the underlying data has occurred.
- Documentation in general has been improved (readers, testing).
- Ferenda now uses the CI service Appveyor to automatically run the entire test suite under Windows on every commit.
- LayeredConfig is now a separate package and not included with Ferenda. It has been generalized and can take any number of configuration sources (in the form of object instances) as initialization arguments. Classes that provide configuration sources from code defaults, INI files, command line arguments, environment variables and more are included. It also has two new class methods, .set and .get.
0.2.0 (released 2014-07-23)¶
This release adds a REST-based HTTP API and includes a lot of infrastructure to support repo-defined querying and aggregation of arbitrary document properties. This also led to a generalization of the TocCriteria class and associated methods, which are now replaced by the Facet class.
The REST API should be considered an alpha version and is definitly not stable.
- The class TocCriteria and the DocumentRepository methods toc_predicates, toc_criteria et al have been removed and replaced with the Facet class and similar methods.
- ferenda.sources.legal.se.direktiv.DirPolopoly and ferenda.sources.legal.se.propositioner.PropPolo has been renamed to ...DirRegeringen and ...PropRegeringen, respectively.
- A REST API enables clients to do faceted querying (ie document whose properties have specified values), full-text search or combinations.
- Several popular RDF ontologies are included and exposed using the REST API. A docrepo can include custom RDF ontologies that are used in the same way. All ontologies used by a docrepo is available as a RDFLib graph from the .ontologies property
- Docrepos can include extra/common data that describes things which your documents refer to, like companies, publishing entities, print series and abstract things like the topic/keyword of a document. This information is provided in the form of a RDF graph, which is also exposed using the REST API. All common data defined for a docrepo is available as the .commondata property.
- New method DocumentRepository.lookup_resource lookup resource URIs from the common data using foaf:name labels (or any other RDF predicate that you might want to use)
- New class Facet and new methods DocumentRepository.facets, .faceted_data, facet_query and facet_seltct to go with that class. These replace the TocCriteria class and the methods DocumentRepository.toc_select, .toc_query, .toc_criteria and .toc_predicates.
- The WSGI app now provides content negotiation using file extensions as well as a the HTTP Accept header, ie. requesting “http://localhost:8000/res/base/123.ttl” gives the same result as requesting the resource “http://localhost:8000/res/base/123” using the “Accept: text/turtle” header.
- New exceptions ferenda.errors.SchemaConflictError and .SchemaMappingError.
- The FulltextIndex class now creates a schema in the underlying fulltext enginge based upon the used docrepos, and the facets that those repos define. The FulltextIndex.update method now takes arbitrary arguments that are stored as separate fields in the fulltext index. Similarly, the FulltextIndex.query method now takes arbitrary arguments that are used to limit the search to only those documents whose properties match the arguments.
- ferenda.Devel has a new ´destroyindex’ action which completely removes the fulltext index, which might be needed whenever its schema changes. If you add any new facets, you’ll need to run ”./ferenda-build.py devel destroyindex” followed by ”./ferenda-build.py all relate –all –force”
- The docrepos ferenda.sources.tech.RFC and W3Standards have been updated with their own ontologies and commondata. The result of parse now creates better RDF, in particular things like dcterms:creator and dcterms:subject not point to URIs (defined in commondata) instead of plain string literals.
- cssmin is no longer bundled within ferenda. Instead it’s marked as a dependency so that pip/easy_install automatically downloads it from pypi.
- The prefix for DCMI Metadata Terms have been changed from “dct” to “dcterms” in all code and documentation.
- testutil now has a Py23DocChecker that can be used with doctest.DocTestSuite() to enable single-source doctests that work with both python 2 and 3.
- New method ferenda.util.json_default_date, usable as the default argument of json.dump to serialize datetime object into JSON strings.
0.1.7 (released 2014-04-22)¶
This release mainly updates the swedish legal sources, which now does a decent job of downloading and parsing a variety of legal information. During the course of that work, a number of changes needed to be made to the core of ferenda. The release is still a part of the 0.1 series because the REST API isn’t done yet (once it’s in, that will be release 0.2)
- CompositeRepository.parse now raises ParseError if no subrepository is able to parse the given basefile.
- ferenda.CompositeRepository.parse no longer requires that all subrepos have storage_policy == “dir”.
- Setting ferenda.DocumentStore.config now updates the associated DocumentStore object with the config.datadir parameter
- New method ferenda.DocumentRepository.construct_sparql_query() allows for more complex overrides than just setting the sparql_annotations class attribute.
- New method DocumentRepository.download_is_different() is used to control whether a newly downloaded resource is semantically different from a previously downloaded resource (to avoid having each ASP.Net VIEWSTATE change result in an archived document).
- New method DocumentRepository.parseneeded(): returns True iff parsing of the document is needed (logic moved from ferenda.decorators.parseifneeded)
- New class variable ferenda.DocumentRepository.required_predicates: Controls which predicates that is expected to be in the output data from .parse()
- The method ferenda.DocumentRepository.download_if_needed() now sets both the If-None-match and If-modified-since HTTP headers.
- The method ferenda.DocumentRepository.render_xhtml() now creates RDFa 1.1
- New ‘compress’ parameter (Can either be empty or “bz2”) controls whether intermediate files are compressed to save space.
- The method ferenda.DocumentStore.path() now takes an extra storage_policy parameter.
- The class ferenda.DocumentStore now stores multiple basefiles in a single directory even when storage_policy == “dir” for all methods that cannot handle attachments (like distilled_path, documententry_path etc)
- New methods ferenda.DocumentStore.open_intermediate(), .serialized_path() and open_serialized()
- The decorator @ferenda.decorators.render (by default called when calling DocumentRepository.parse()) now serialize the entire document to JSON, which later can be loaded to recreate the entire document object tree. Controlled by config parameter serializejson.
- The decorator @ferenda.decorators.render now validates that required triples (as determined by .required_predicates) are present in the output.
- New decorator @ferenda.decorators.newstate, used in ferenda.FSMParser
- The docrepo ferenda.Devel now has a new csvinventory action
- The functions ferenda.Elements.serialize() and .deserialize() now takes a format parameter, which can be either “xml” (default) or “json”. The “json” format allows for full roundtripping of all documents.
- New exception ferenda.errors.NoDownloadedFileError.
- The class ferenda.PDFReader now handles any word processing format that OpenOffice/LibreOffice can handle, by first using soffice to convert it to a PDF. It also handles PDFs that consists entirely of scanned pages without text information, by first running the images through the tesseract OCR engine. Finally, a new keep_xml parameter allows for either removing the intermediate XML files or compressing them using bz2 to save space.
- New method ferenda.PDFReader.is_empty()
- New method ferenda.PDFReader.textboxes() iterates through all textboxes on all pages. The user can provide a glue function to automatically concatenate textboxes that should be considered part of the same paragraph (or other meaningful unit of text).
- New debug method ferenda.PDFReader.drawboxes() can use the same glue function, and creates a new pdf with all the resulting textboxes marked up. (Requires PyPDF2 and reportlab, which makes this particular feature Python 2-only).
- ferenda.PDFReader.Textbox objects can now be added to each other to form larger Textbox objects.
- ferenda.Transformer now optionally logs the equivalent xsltproc command line when transforming using XSLT.
- new method ferenda.TripleStore.update(), performs SPARQL UPDATE/DELETE/DROP/CLEAR queries.
- ferenda.util has new gYearMonth and gYear classes that subclass datetime.date, but are useful when handling RDF literals that should have the datatype xsd:gYearMonth (or xsd:gYear)
0.1.6.1 (released 2013-11-13)¶
This hotfix release corrected an error in setup.py that prevented installs when using python 3.
0.1.6 (released 2013-11-13)¶
This release mainly contains bug fixes and development infrastructure changes. 95 % of the main code base is covered through the unit test suite, and the examples featured in the documentation is now automatically tested as well. Whenever discrepancies between the map (documentation) and reality (code) has been found, reality has been adjusted to be in accordance with the map.
The default HTML5 theme has also been updated, and should scale nicely from screen widths ranging from mobile phones in portrait mode to wide-screen desktops. The various bundled css and js files has been upgraded to their most recent versions.
- The DocumentStore.open_generated method was removed as noone was using it.
- The (non-documented) modules legalref and legaluri, which were specific to swedish legal references, have been moved into the ferenda.sources.legal.se namespace
- The (non-documented) feature where CSS files specified in the configuration could be in SCSS format, and automatically compiled/transformed, has been removed, since the library used (pyScss) currently has problems on the Python 3 platform.
- The ferenda.Devel.mkpatch() command now actually works.
- The republishsource configuration parameter is now available, and controls whether your Atom feeds link to the original document file as it was fetched from the source, or to the parsed version. See Configuration.
- The entire RDF dataset for a particular docrepo is now available through the ReST API in various formats using the same content negotiation mechanisms as the documents themselves. See The WSGI app.
- ferenda-setup now auto-configures indextype (and checks whether ElasticSearch is available, before falling back to Whoosh) in addition to storetype.
0.1.5 (released 2013-09-29)¶
Documentation, particularly code examples, has been updated to better fit reality. They have also been added to the test suite, so they’re almost guaranteed to be updated when the API changes.
Transformation of XHTML1.1+RDFa files to HTML5 is now done using the new Transformer class, instead of the DocumentRepository.transform_to_html method, which has been removed
DocumentRepository.list_basefiles_for (which was a shortcut for calling list_basefiles_for on the docrepos’ store object) has been removed. Typical change needed:
- for basefile in self.list_basefiles_for("parse"): + for basefile in self.store.list_basefiles_for("parse"):
- New ferenda.Transformer class (see above)
- A new decorator, ferenda.decorators.downloadmax, can be used to limit the maximum number of documents that a docrepo will download. It looks for eitther the “FERENDA_DOWNLOADMAX” environment variable or the downloadmax configuration parameteter. This is primarily useful for testing and trying out new docrepos.
- DocumentRepository.render_xhtml will now include RDFa statements for all (non-BNode) subjects in doc.meta, not just the doc.uri subject. This makes it possible to state that a document is written by some person or published by some entity, and then include metadata on that person/entity. It also makes it possible to describe documents related to the main document, using the information gleaned from the main document
- DocumentStore now has a intermediate_path method – previously some derived subclasses implemented their own, but now it’s part of the base class.
- ferenda.errors.DocumentRemovedError now has a dummyfile attribute, which is used by ferenda.manager.run to avoid endless re-parsing of downloaded files that do not contain an actual document.
- A new shim module, ferenda.compat (modelled after six.moves), simplified imports of modules that may or may not be present in the stdlib depending on python version. So far, this includes OrderedDict, unittest and mock.
- Most of the bundled document repository classes in ferenda.sources has been overhauled and adapted to the changes that has occurred to the API since the old days.
- Continous integration and coverage is now set up with Travis-CI (https://travis-ci.org/staffanm/ferenda/) and Coveralls (https://coveralls.io/r/staffanm/ferenda)
0.1.4 (released 2013-08-26)¶
- ElasticSearch is now supported as an alternate backend to Whoosh for fulltext indexing and searching.
- Documentation, particularly “Creating your own document repositories” have been substantially overhauled, and in the process various bugs that prevented the usage of custom SPARQL queries and XSLT transforms were fixed.
- The example RFC docrepo parser has been improved.
0.1.3 (released 2013-08-11)¶
- Search functionality when running under WSGI is now implemented. Still a bit basic and not really customizable (everything is done by manager._wsgi_search), but seems to actually work.
- New docrepo: ferenda.sources.general.Static, for publishing static content (such as “About”, “Contact”, “Legal info”) that goes into the site footer.
- The FulltextIndex class have been split up similarly to TripleStore and the road has been paved to get alternative implementations that connect to other fulltext index servers. ElasticSearch is next up to be implemented, but is not done yet.
- General improvement of documentation
0.1.2 (released 2013-08-02)¶
- If using a RDFLib based triple store (storetype=”SQLITE” or “SLEEPYCAT”), when generating all documents, all triples are read into memory, which speeds up the SPARQL querying considerably
- The TripleStore class has been overhauled and split into subclasses. Also gained the above inmemory functionality + the possibility of using command-line curl instead of requests when up/downloading large datasets.
- Content-negotiation when using the WSGI app (as described in doc/wsgi.rst) is supported
0.1.1 (released 2013-07-27)¶
This release fixes a bug with TOC generation on python 2, creates a correct long_description for pypi and adds some uncommitted CSS improvements. Running the finished site under WSGI is now tested and works ok-ish (although search is still unimplemented).
0.1.0 (released 2013-07-26)¶
This is just a test release to test out pypi uploading as well as git branching and tagging. Neverthless, this code is approaching feature completeness, except that running a finished site under WSGI hasn’t been tested. Generating a static HTML site should work OK-ish.
