===== OpenOfficePlugin =====
//Top level [[index|plugin]] that uses Open Office to convert various types of documents.//

  * Processes files with extensions: ''.doc'', ''.dot'', ''.docx'', ''.odt'', ''.wpd'', ''.ppt'', ''.pptx'', ''.odp'', ''.rtf'', ''.xls'', ''.xlsx'', ''.ods'' \\ Perl regular expression: //''<nowiki>(?i).(doc|dot|docx|odt|wpd|ppt|pptx|odp|rtf|xls|xlsx|ods)$</nowiki>''//

The OpenOfficePlugin is an extension that is available for Greenstone. It is useful for processing both Open Office and Microsoft Office documents, as well as other text formats.

With OpenOffice and the extension installed and the Greenstone environment set up for this, 
the OpenOfficePlugin will be available.

Furthermore, an OpenOfficeConverter helper plugin provides a new option for Greenstone's Word, PowerPoint and Excel Plugins, 
''-openoffice_conversion'', allowing conversion with Open Office instead of the existing 
converter. Switching on this new option means that more recent Office formats like 
''docx'' can be included in Greenstone collections and processed by Greenstone.


==== Installing OpenOffice ====


To use OpenOfficePlugin or [[OpenOfficeConverter]], you must first install 
[[http://www.openoffice.org/| Open Office]]. Once Open Office is installed, you may have to set the environment variables so Greenstone can find OpenOffice:
===Linux ===
  * If SOFFICE_HOME is not set, set it to the full path to your OpenOffice folder.
=== Windows ===
  * In the Start Menu, type "environment" in the search box and select ''Edit environment variables for your account''
  * In the Environment Variables window, press ''New...'' under the User variables section. For Variable name, enter ''SOFFICE_HOME''. For Variable value, enter the full path to your OpenOffice folder (for example ''C:\Program Files (x86)\OpenOffice 4'') and click ''OK''.
  * If there is a ''Path'' variable in the User variables section, select this and press ''Edit...''. Add '';%SOFFICE_HOME%\program'' to the end of the Variable value and click ''OK''.
  * If there is NOT a ''Path'' variable in the User variables section, press ''New...''. For Variable name, enter ''Path''. For Variable value, enter ''%SOFFICE_HOME%\program;%Path%'' and click ''OK''.
  * Click ''OK'' in the Environment Variables window to save your changes. 


==== Installing OpenOffice Extension ====

Once you have Open Office set up, download the Greenstone extension for it 
[[http://trac.greenstone.org/browser/gs2-extensions/open-office/trunk|from here]], 
which is available in tar.gz and zip formats, and unzip into Greenstone's ''gs2build/ext'' folder.

If you have Greenstone open during this, be sure to completely exit both the GLI and the
server and restart Greenstone in order for the extension to become available in the Greenstone 
environment.

Note that you cannot already 
have an instance of OpenOffice running when using GLI: you will need to terminate any
 previously running instance. It is also unlikely that you can get a separate instance of 
OpenOffice running after quitting GLI. If you wish to do so, you will need to use Task 
Manager to terminate the open office process launched by the extension upon running GLI.




==== Plugin options ====
The following table lists all of the configuration options available for OpenOfficePlugin. 

^Option^Description^Value^
^//OpenOfficePlugin Options//^^^
| **process_exp** |A perl regular expression to match against filenames. Matching filenames will be processed by this plugin. For example, using '(?i).html?\$' matches all documents ending in .htm or .html (case-insensitive). |//Default: (?i).(doc|dot|docx|odt|wpd| ppt|pptx|odp|rtf| xls|xlsx|ods)$// |
^//Options Inherited from [[OpenOfficeConverter]]//^^^
| **openoffice_port** |Port number for... |//Default: 8100// //Range: 81,// |
^//Options Inherited from [[BaseMediaConverter]]//^^^
| **enable_cache** |Cache automatically generated files (such as thumbnails and screen-size images) so they don't need to be repeatedly generated. | |
^//Options Inherited from [[ConvertBinaryFile]]//^^^
| **convert_to** |(REQUIRED) Plugin converts to TEXT or HTML or various types of Image (e.g. JPEG, GIF, PNG). |//Default: auto//\\ [[ConvertBinaryFile#convert_to option values|List]] |
| **keep_original_filename** |Keep the original filename for the associated file, rather than converting to doc.pdf, doc.doc etc. | |
| **title_sub** |Substitution expression to modify string stored as Title. Used by, for example, PDFPlugin to remove "Page 1", etc from text used as the title. | |
| **apply_fribidi** |Run the "fribidi" Unicode Bidirectional Algorithm program over the converted file (for right-to-left text). | |
| **use_strings** |If set, a simple strings function will be called to extract text if the conversion utility fails. | |
^//Options Inherited from [[AutoExtractMetadata]]//^^^
| **first** |Comma separated list of numbers of characters to extract from the start of the text into a set of metadata fields called 'FirstN', where N is the size. For example, the values "3,5,7" will extract the first 3, 5 and 7 characters into metadata fields called "First3", "First5" and "First7". | |
^//Options Inherited from [[AcronymExtractor]]//^^^
| **extract_acronyms** |Extract acronyms from within text and set as metadata. | |
| **markup_acronyms** |Add acronym metadata into document text. | |
^//Options Inherited from [[KeyphraseExtractor]]//^^^
| **extract_keyphrases** |Extract keyphrases automatically with Kea (default settings). | |
| **extract_keyphrases_kea4** |Extract keyphrases automatically with Kea 4.0 (default settings). Kea 4.0 is a new version of Kea that has been developed for controlled indexing of documents in the domain of agriculture. | |
| **extract_keyphrase_options** |Options for keyphrase extraction with Kea. For example: mALIWEB - use ALIWEB extraction model; n5 - extract 5 keyphrase;, eGBK - use GBK encoding. | |
^//Options Inherited from [[EmailAddressExtractor]]//^^^
| **extract_email** |Extract email addresses as metadata. | |
^//Options Inherited from [[DateExtractor]]//^^^
| **extract_historical_years** |Extract time-period information from historical documents.  This is stored as metadata with the document. There is a search interface for this metadata, which you can include in your collection by adding the statement, "format QueryInterface DateSearch" to your collection configuration file. | |
| **maximum_year** |The maximum historical date to be used as metadata (in a Common Era date, such as 1950). |//Default: 2013// |
| **maximum_century** |The maximum named century to be extracted as historical metadata (e.g. 14 will extract all references up to the 14th century). |//Default: -1// |
| **no_bibliography** |Do not try to block bibliographic dates when extracting historical dates. | |
^//Options Inherited from [[GISExtractor]]//^^^
| **extract_placenames** |Extract placenames from within text and set as metadata. Requires GIS extension to Greenstone. | |
| **gazetteer** |Gazetteer to use to extract placenames from within text and set as metadata. Requires GIS extension to Greenstone. | |
| **place_list** |When extracting placements, include list of placenames at start of the document. Requires GIS extension to Greenstone. | |
^//Options Inherited from [[BasePlugin]]//^^^
| **process_exp** |A perl regular expression to match against filenames. Matching filenames will be processed by this plugin. For example, using '(?i).html?\$' matches all documents ending in .htm or .html (case-insensitive). | |
| **no_blocking** |Don't do any file blocking. Any associated files (e.g. images in a web page) will be added to the collection as documents in their own right. | |
| **block_exp** |Files matching this regular expression will be blocked from being passed to any later plugins in the list. | |
| **store_original_file** |Save the original source document as an associated file. Note this is already done for files like PDF, Word etc. This option is only useful for plugins that don't already store a copy of the original file. | |
| **associate_ext** |Causes files with the same root filename as the document being processed by the plugin AND a filename extension from the comma separated list provided by this argument to be associated with the document being processed rather than handled as a separate list. | |
| **associate_tail_re** |A regular expression to match filenames against to find associated files. Used as a more powerful alternative to associate_ext. | |
| **OIDtype** |The method to use when generating unique identifiers for each document. |//Default: auto//\\ [[BasePlugin#OIDtype option values|List]] |
| **OIDmetadata** |Specifies the metadata element that hold's the document's unique identifier, for use with -OIDtype=assigned. |//Default: dc.Identifier// |
| **no_cover_image** |Do not look for a prefix.jpg file (where prefix is the same prefix as the file being processed) to associate as a cover image. | |
