lpOD 0.9.0 is released

lpOD 0.9.0 has just been released, together with its documentation. You can download lpOD 0.9 here.

LpOD 0.9.0

lpOD -- languages & platforms OpenDocument. Definition of a Free Software API implementing the ISO/IEC 26300 standard. Development, for higher level use cases, in Python, Perl and Ruby languages. of a top-down oriented API.

This release focuses on style and table support, and polishing the existing API. Command-line tools were greatly improved and enriched.

Low-level API

  • Default numeric types were added, targeting the French locale for now.
  • The text API is now richer.

High-level API

  • Started to implement a templating language in the content of ODF documents. Only setting values and "if" are implemented for now, and only on text.

    You can see an example template in "python/templates/test_template.ott" and an example script in "python/templates/test_template.py".

    Templating the metadata is left as an exercise to the interested reader.

  • Tables of content can now be filled with the titles found in the document.

  • Draw page can use transitions (fade by default).

  • Tables are quite faster and easier to use since you can access any row/column/cell without having to expand the table first.

  • Most high-level elements support outputting reStructuredText representation.

  • Medium-complexity reStructuredText documents can be converted to ODT, from scratch or appended to an existing document (docutils required).

Command-line Utilities

  • The lpod-show.py tool dumps a textual representation of the content (informal or reStructuredText). It can also dump the latter, images, style information and metadata list in a directory.
  • The lpod-style.py introspection tool shows the list of styles of the document, whether it is used, and is able to remove them all. It can also merge styles from one document to another.
  • The lpod-meta.py introspection tool can list and edit metadata of the document.
  • The lpod-merge.py tool can merge documents of the same type. ODT, ODS and CSV and supported for now. ODP to come.
  • The lpod-highlight.py tool can apply a style on a text pattern. The default style is overlining as if you were using a yellow highlighter pen.
  • The lpod-mm2odt.py tool converts XML mind-map files to ODT.
  • The lpod-rst2odt.py tool converts reStructuredText document to ODT.

Documentation

  • 80 % of the documentation is implemented. There is still much work on the styles part.

Packaging

  • PKGBUILD and ebuild packages contributed. Deb and RPM to come.

Statistics: from v0.8 to v0.9.0

lpOD 0.8 is released

lpOD 0.8 has just been released, together with its documentation. You can download lpOD 0.8 here.

lpOD -- languages & platforms OpenDocument.
Definition of a Free Software API implementing the ISO/IEC 26300 standard.
Development, for higher level use cases, in Python, Perl and Ruby languages.
of a top-down oriented API.

  • The architecture design is complete.
  • The functional lpOD coverage is 90% complete.
  • Only Python implementation is available (80% complete), and serves as the  reference implementation
  • This release starts providing command-line tools for introspection and manipulation.
  • The documentation is now online http://docs.lpod-project.org
  • Cookbooks provide ready-to-use examples of the API for ODT, ODS and ODP (tables, tocs, notes, images frames, slides transitions, shapes, ... )

Python Implementation

Low-level API

  • All types of styles are supported in the low-level API.
  • Text search and replace API is added
  • Basic shapes can be created: ellipse and circle, rectangle and square, and line.
  • Adding non ODF resources (e.g. images, pdf, ...) in documents
  • A Virtual File System (VFS) layer handles grabbing document from HTTP and FTP.
  • After starting with the libxml2 Python wrapper, switched to lxml for both speed and ease of use.

High-level API

  • Template are provided, with empty body, i.e. the ODT template has no paragraph, the ODS template has no table and the ODP template has no draw page.
  • A document can grab styles from another document to merge them with its own ones.
  • A specific API is available on paragraphs to insert notes and annotation.
  • A specific API is available for tables to abstract the XML model, e.g. you can access cell "C3" without knowning the storage.
  • Tables can be created from and exported to CSV.
  • The full API to metadata is available. Only RDF would be missing.
  • The navigation API no longer use a context element. The element itself is the navigation API.

Command-line Utilities

  • The lpod-show.py tool dumps a textual representation of the content. It can also dump the latter, style information and metadata list in a directory.
  • The lpod-meta.py introspection tool can list and edit metadata of the document.
  • The lpod-merge.py tool can merge documents of the same type. ODT, ODP, ODS and CSV and supported for now.
  • The lpod-highlight.py tool can apply a style on a text pattern. The default style is overlining as if you were using a yellow highlighter pen.

Statistics: from v0.7 to v0.8

Final countdown until the first lpOD release!

The first public release of lpOD will be available during the week of the 26th of October.  lpOD is released under the GPL v3 and the Apache v2.0 licenses. Code repository and mailing lists will be progressively rolled out during the year.

Feel free to contact our team if you have any question.

The lpOD way

Summary

The lpOD way

  • Plurilinguistic approach:
    • Definition of a common feature set before the development starts
    • Free Software
  • Validation of advanced users' needs:
    • scientific laboratories
    • industrial scale users
  • Project management:
    • Short iterations
    • XP-style programming
    • Free Software development methods.

Problem Statement

The expected benefits of ODF depend however in a large way from the strengtening of development infrastructures and entities able to use the format and innovate on it.

The toolkits available today for ODF are somewhat limited to a traditional scope of office applications and tend to lag behind in the following areas:

  • entreprise needs (business intelligence, document management...)
  • use cases (highly collaborative environments, nomadic uses, SOA, REST...)
  • standard's specification (implementation scope and features' span)

Proposed Solution

The lpOD project contributes to the expansion of the OpenDocument Format ecosystem through its implementation of the ISO standard ISO/IEC 26300.

  • Defining a Free Software API for the ISO standard ISO/IEC 26300 (ODF)
  • Developing and validating an implementation for higher level use cases

The main characteristics of the lpOD project's are:

  • Cooperation with the OASIS Consortium's ODF Technical Committees and the ODF Toolkit's Union.
  • Multilingual approach (Python, Perl, Ruby) with
    • upstream design of the common base
    • Free Software development: GPL v3, Apache V2.0
  • Validation of advanced users' needs by research laboratories and corporate users
  • Software development project management based on short iterations, Xtreme programming and Free Software practices.

The general approach to this project relies on four main principles:

  • Strict implementation of the ISO/IEC 26300 standard
  • Business needs validation for high level features
  • Development of Free Software libraries
  • Libraries are designed for REST services
