You can integrate WIRED into your application in two ways:

1. Analysis programs written in Java or its related technology can directly use the WIRED class library.
2. Other programs can interface to WIRED via XML.

• The easiest way to get started with WIRED (for us) was via XML.
• XML is the W3 Consortium's standard for describing data (not only text) that has to be sent over the net.
• XML is a good language for describing data that has a tree structure, such as events and detector geometry.
• It is ASCII and can be edited with any editor on any platform.
• By using XML to describe data and the detector geometry, WIRED can be made independent of a particular experiment's format.
• The DTD (document type definition, or grammar) of the XML language to describe LHCb events (lhcbevent.dtd, lhcb_r0_e0.xml) , and detector geometry (lhcbgeometry.dtd, lhcb.xml).
• Events are made up of vertices (with id and spatial coordinates), inside which are nested other vertices and tracks (with particle names and momenta).
• The geometry is made up of nested parts belonging to subdetectors. Each part is eventually described by geometrical shapes (polylines, circles, arcs etc.).
