Editing Universal Network Objects

'''Universal Network Objects''' ('''UNO''') is the [[software component|component model]] used in the [[OpenOffice.org]] and [[LibreOffice]] computer software [[application suite]]s. It is interface-based and designed to offer interoperability between different [[programming language]]s, object models and machine architectures, on a single machine, within a LAN or over the Internet.

Users can implement or access UNO components from any programming language for which a [[language binding]] exists. Complete UNO language bindings exist for [[C++]] (compiler-dependent), [[Java (programming language)|Java]], [[Object REXX]], [[Python (programming language)|Python]], and [[Tcl (programming language)|Tcl]]. Bindings allowing access, but not writing, to components exist for [[StarOffice Basic]], [[OLE Automation]] and the [[Microsoft .NET|.NET]] [[Common Language Infrastructure]]. In particular, this API is used by macros.

Universal Network Objects operate within the UNO Runtime Environment (URE).<ref>{{ cite web | url = http://svn.apache.org/repos/asf/openoffice/ooo-site/trunk/content/l10n/archive/Universal_i18n_framework.pdf | title = Universal I18n Framework for Office Applications: Technical Overview | first = Dieter | last = Loeschky |author2=Shanmugam Senthil  | year = 2001 | publisher = Sun Microsystems | location = Palo Alto | pages = 1–26 [8] | format = PDF | access-date = 18 May 2010 }}</ref>

The [[Apache OpenOffice]] version of UNO is released under the terms [[Apache License]] (Version 2) as [[free and open source software]].

== UNO for function-calling ==
Examples: an external program can export an [[OpenDocument|ODT]] file as a [[PDF]] file, or import and convert a [[Office Open XML|DOCX]], calling LibreOffice by the UNO interface.  Another external program can access a cell and formulas from LibreOffice Calc file.

Application examples: ''Docvert'',<ref>{{cite web|url=http://holloway.co.nz/docvert/|title=Docvert - Office to Open Standards|website=holloway.co.nz|publisher=Bronwyn Holloway-Smith|access-date=20 September 2014}}</ref> ''JODConverter'',<ref>{{cite web|url=https://github.com/sbraconnier/jodconverter/wiki/Getting-Started|title=JODConverter|website=jodconverter.com|access-date=5 September 2017}}</ref> ''unoConv''.<ref>{{cite web|url=http://dag.wieers.com/home-made/unoconv/|title=DAG: unoconv: Convert between any document format supported by OpenOffice|publisher=Dag Wieërs|access-date=20 September 2014}}</ref>

== UNO for Add-Ons ==
Programmers can write and integrate their own UNO components to OpenOffice/LibreOffice. Those components can be added to the LibreOffice menus and toolbars; they are called "Add-Ons".<ref name="unowiki">{{cite web|url=http://help.libreoffice.org/Common/Integrating_new_UNO_components|title=Integrating new UNO components|access-date=20 September 2014}}</ref>
The Add-Ons can extend the functionality of LibreOffice.

The integration of new components is supported by some tools and services. The three main steps are as follows:<ref name="unowiki"/>

#Register the new components within LibreOffice. This can be accomplished using the tool <code>unopkg</code>.
#Integrate the new components as services. The ProtocolHandler and JobDispatch services assist you.
#Change the user interface (menus or toolbars). This can be done almost automatically by writing an XML text file that describes the changes.

Application example: ''jOpenDocument''.<ref>{{cite web|url=http://www.jopendocument.org/|title=jOpenDocument Homepage. Open Document library|access-date=20 September 2014}}</ref>
