Entry Levels |

The entries in TBX-ISO-TML are structured in three hierarchical levels commonly referred to as the concept, language, and term levels. The various data categories are associated with certain levels. The concept level corresponds to the `<tbx:termEntry>` element and its immediate children, the language level corresponds to the `<tbx:langSet>` element and its immediate children, and the term level corresponds to the `<tbx:tig>` element and its immediate children. The elements at the term level must be entered in the order specified for <tbx:tig> The following sample entry shows the levels and several of their associated data categories. In this sample, only xGraphic occurs at the concept level, a note and a definition occur at the language level, and data categories that describe terms, such as part of speech, normative authorization and usage note occur at the term level. There are two language sections provided for demonstration purposes, one for English and one (empty here) for French. `<tbx:termEntry id="ISO10241-1.a22.31"> <tbx:xGraphic xtarget="http://example.com/graphic/ctr-open-exh.png"/> <tbx:langSet xml:lang="en"> <tbx:note>Buoyancy was first described in the Archimedes principle in 212 B.C.</tbx:note> <tbx:definition>resultant of upward forces, exerted by the water on a submerged or floating body, equal to the weight of the water displaced by this body</tbx:definition> <tbx:tig> <tbx:term id="a22.31-1">buoyancy</tbx:term> <tbx:partOfSpeech value="noun"/> <tbx:normativeAuthorization value="preferredTerm"/> <tbx:usageNote>Having a property of buoyancy is referred to as "buoyant".</tbx:usageNote> </tbx:tig> <tbx:tig> <tbx:term id="a22.31-2">floatability</tbx:term> <tbx:partOfSpeech value="noun"/> <tbx:normativeAuthorization value="deprecatedTerm"/> </tbx:tig> </tbx:langSet> <tbx:langSet xml:lang="fr"> ... </tbx:langSet > </tbx:termEntry>`
