OpenOffice/LibreOffice integration

Introduction
This feature offers an interface for inserting citations and formatting a Bibliography in an OpenOffice or LibreOffice Writer document from JabRef.
Throughout this help document, whenever the name OpenOffice is used, it can be interchanged with LibreOffice.
Using the OpenOffice/LibreOffice interface
To communicate with OpenOffice, JabRef must first connect to a running OpenOffice instance. You need to start OpenOffice and enter your document before connecting from JabRef.
JabRef needs to know the location of your OpenOffice executable (soffice.exe on Windows, and soffice on other platforms), and the directory where several OpenOffice jar files reside. If you connect by clicking the Connect button, JabRef will try to automatically determine these locations. If this does not work, you need to connect using the Manual connect button, which will open a window asking you for the needed locations.
After the connection has been established, you can insert citations by selecting one or more entries in JabRef and using the Push to OpenOffice button in the dropdown menu of JabRef's toolbar, or by using the appropriate button in the OpenOffice panel in the side pane. This will insert citations for the selected entries at the current cursor position in the OpenOffice document, and update the bibliography to contain the full reference.
Note: JabRef does not use OpenOffice's built-in bibliography system, because of the limitations of that system. A document containing citations inserted from JabRef will not generally be compatible with other reference managers such as Bibus and Zotero.
Two different types of citations can be inserted - either a citation in parenthesis, "(Author 2007)", or an in-text citation, "Author (2007)". This distinction is only meaningful if author-year citations are used instead of numbered citations, but the distinction will be preserved if you switch between the two styles.
If you modify entries in JabRef after inserting their citations into OpenOffice, you will need to synchronize the bibliography. By default, Automatically sync bibliography when inserting citations is enabled. This can be disabled by clicking the Settings button and unchecking Automatically sync bibliography when inserting citations. The Sync OO bibliography button will update all entries of the bibliography, provided their citation keys have not been altered (JabRef encodes the citation key into the reference name for each citation to keep track of which citation key the original JabRef entry has).
The style file
To customize the citation style you need to select a style file, or use one of the default styles. The style defines the format of citations and the format of the bibliography. You can use standard JabRef export formatters to process fields before they are sent to OpenOffice. Through the style file, the intention is to give as much flexibility in citation styles as possible. You can switch style files at any time, and use the Update button to refresh your bibliography to follow the new style.
By clicking the Select style button you can bring up a window that allows selection of either the default style or an external style file. If you want to create a new style based on the default, you can click the View button to bring up the default style contents, which can be copied into a text editor and modified.
To choose an external style file, you have two options. Either you can choose a style file directly, or you can set a style file directory. If you do the latter, you will see a list of styles from that directory (and subdirectories), and can choose one from that list.
To edit an already loaded custom style file or to reload changes that you made to a style file, click on Select style to bring up the style selection window, then right-click the currently loaded file to bring up a menu that allows you to choose either "Edit" or "Reload".
CAUTION: Please take care that your style file is saved using UTF-8 for character encoding. If you use another character encoding (even other unicode encodings such as UTF-16 or UTF-32), JabRef will not be able to process your style file.
Here is an example style file:

(Note that the layout for each entry type must be constrained to a single line in the style file - above, the lines are broken up to improve readability.)
Regarding tool support, there is the Export-Filter-Editor for Jabref to quickly create a style file.
Global properties
The PROPERTIES section describes global properties for the bibliography. The following table describes the available properties:

CitationSeparator
string
;
Text inserted between items when a citation contains multiple entries, e.g. [Smith 2001; Jones 2002]
EtAlString
string
et al.
Text inserted after author names when not all authors are listed, e.g. [Smith et al. 2001]
FormatCitations
boolean
false
Determines whether formatting should be applied to citations. If true, a character format will be applied to the citations. The property CitationCharacterFormat controls which format should be applied, and the given format must be defined in your OpenOffice document. Any font settings and effects can be chosen within OpenOffice for your chosen character format.
GroupedNumbersSeparator
string
-
Text inserted between numbers when numbered citations are grouped, e.g. [4-6]
InTextYearSeparator
string
Single Space
Text inserted between author names and starting bracket before year in in-text citations.
ItalicEtAl
boolean
true
If true, the "et al." string in citation markers is italicized.
MaxAuthors
integer
3
The maximum number of authors to list in a citation that has appeared earlier in the document.
MaxAuthorsFirst
integer
3
The maximum number of authors to list in a citation when appearing for the first time.
MinimumGroupingCount
integer
3
The minimum number of consecutive entries a citation should contain before the numbers are grouped, e.g. [4-6] vs. [4; 5; 6].
MultiCiteChronological
boolean
true
If true, multiple entries in the same citation are sorted chronologically, otherwise they are sorted alphabetically.
If numbered entries are used, the BracketBefore and BracketAfter properties are the most important - they define which characters the citation number is wrapped in. The citation is composed as follows: [BracketBefore][Number][BracketAfter] where [Number] is the number of the citation, determined according to the ordering of the bibliography and/or the position of the citation in the text. If a citation refers to several entries, these will be separated by the string given in the property CitationSeparator (for instance, if CitationSeparator=;, the citation could look like [2;4;6]). If two or more of the entries have a series of consecutive numbers, the numbers can be grouped (for instance [2-4] for 2, 3 and 4 or [2;5-7] for 2, 5, 6 and 7). The property GroupedNumbersSeparator (default -) determines which string separates the first and last of the grouped numbers. The integer property MinimumGroupingCount (default 3) determines what number of consecutive numbers is required before entries are grouped. If MinimumGroupingCount=3, the numbers 2 and 3 will not be grouped, while 2, 3, 4 will be. If MinimumGroupingCount=0, no grouping will be done regardless of the number of consecutive numbers.
If numbered entries are not used, author-year citations will be created based on the citation properties. A parenthesis citation is composed as follows: [BracketBefore][Author][YearSeparator][Year][BracketAfter] where [Author] is the result of looking up the field or fields given in the AuthorField property, and formatting a list of authors. The list can contain up to MaxAuthors names - if more are present, the list will be composed as the first author plus the text specified in the property EtAlString. If the property MaxAuthorsFirst is given, it overrides MaxAuthors the first time each citation appears in the text.
If several, slash-separated, fields are given in the AuthorField property, they will be looked up successively if the first field is empty for the given entry. In the example above, the "author" field will be used, but if empty, the "editor" field will be used as a backup.
The names in the author list will be separated by the text given by the AuthorSeparator property, except for the last two names, which will be separated by the text given by AuthorLastSeparator. If the property AuthorLastSeparatorInText is given, it overrides the former for citations of the in-text type. This makes it possible to get citations like (Olsen & Jensen, 2008) and Olsen and Jensen (2008) for the same style.
[Year] is the result of looking up the field or fields given in the [YearField] property.
An in-text citation is composed as follows: [Author][InTextYearSeparator][BracketBefore][Year][BracketAfter] where [Author] and [Year] are resolved in exactly the same way as for the parenthesis citations.
If two different cited sources have the same authors and publication year, and author-year citations are used, their markers will need modification in order to be distinguishable. This is done automatically by appending a letter after the year for each of the publications; 'a' for the first cited reference, 'b' for the next, and so on. For instance, if the author "Olsen" has two cited papers from 2005, the citation markers will be modified to (Olsen, 2005a) and (Olsen, 2005b). In the bibliography layout, the placement of the "uniquefier" letter is indicated explicitly by inserting the virtual field uniq.
If several entries that have been "uniquefied" are cited together, they will be grouped in the citation marker. For instance, of the two entries in the example above are cited together, the citation marker will be (Olsen, 2005a, b) rather than Olsen, 2005a; Olsen, 2005b). The grouped uniquefier letters (a and b in our example) will be separated by the string specified by the UniquefierSeparator property.
Author-year citations referring more than one entry will by default be sorted chronologically. If you wish them to be sorted alphabetically, the citation property MultiCiteChronological should be set to false..
Reference list layout
The LAYOUT section describes how the bibliography entry for each entry type in JabRef should appear. Each line should start with either the name of an entry type, or the word default, followed by a '='. The default layout will be used for all entry types for which an explicit layout hasn't been given.
The remainder of each line defines the layout, with normal text and spaces appearing literally in the bibliography entry. Information from the entry is inserted by adding \field markers with the appropriate field name (e.g. \author for inserting the author names). Formatting information for the field can be included here, following JabRef's standard export layout syntax. Refer to JabRef's documentation on custom export filters for more information about which formatters are available and tooling hints.
If author-year citations are used, you have to explicitly specify the position of the "uniquefier" letter that is added to distinguish similar-looking citations. This is done by including a marker for the virtual field uniq, typically right after the year (as shown in the example style file). The uniq field is automatically set correctly for each entry before its reference text is laid out.
To indicate formatting in the bibliography, you can use the HTML-like tag pairs <b> </b>, <i> </i>, <sup> </sup> and <sub> </sub> to specify bold text, italic text, superscript and subscript, respectively.
If you are using numbered citations, the number for each entry will be automatically inserted at the start of each entry in the reference list. By default, the numbers will be enclosed in the same brackets defined for citations. The optional citation properties BracketBeforeInList and BracketAfterInList override BracketBefore and BracketAfter if set. These can be used if you want different types of brackets (or no brackets) in the reference list. Note that these need not be brackets as such - they can be any combination of characters.
Known issues
Make sure to save your Writer document in OpenDocument format (odt). Saving to Word format will lose your reference marks.
Otherwise try to use the external tool JabRef LibreOffice Converter. This LibreOffice extension converts the reference marks to code that can be saved.
There is currently no support for footnote based citations.
The cursor may be poorly positioned after inserting a citation.
Copy-pasting the example style file directly from this page can give an unparseable file. To avoid this, instead download the example file from the link in the download section.
Make sure that libreoffice-java-common is installed on Linux for LibreOffice 5, otherwise important libraries are missing.
The snap version of LibreOffice and JabRef may cause connection issues. Try to use the *deb versions instead.
Open Office 4 will only work running under a 32-bit Java JRE/JDK on Windows because there is no 64-bit version of OpenOffice yet.
