 This section describes the default data model defined in the \file{blx-dm.def} file which is part of \path{biblatex}. The data model is defined using the macros documented in \secref{aut:ctm:dm}. It is possible to redefine the data model which both \biblatex and \biber use so that datasources can contain new entrytypes and fields (which of course will need style support). The data model specification also allows for constraints to be defined so that data sources can be validated against the data model (using \biber's \opt{--validate-datamodel} option). Users who want to customise the data model need to look at the \file{blx-dm.def} file and to read \secref{aut:ctm:dm}.
 
+All entry types and field names are given in all-lowercase form here. This is how the entry types and field names are given in the data model. While the \biber/\bibtex input side is case insensitive, the \latex side is case sensitive and uses the exact capitalisation from the data model. This means that the input in the \file{bib} file may use any capitalisation of entry types and field names, but when the fields are used in the \latex document---for example in \cmd{citefield}---the capitalisation must match the captalisation in the data model, for standard types and fields that would be all lowercase.

 The default data model is defined in the core \biblatex file \file{blx-dm.def} using the macros described in this section. The default data model is described in detail in \secref{bib}. The data model is used internally by \biblatex and also by the backend. In practice, changing the data model means that you can define the entrytypes and fields for your datasources and validate your data against the data model. Naturally, this is not much use unless your style supports any new entrytypes or fields and it raises issues of portability between styles (although this can be mitigated by using the dynamic data modification functionality described in \secref{aut:ctm:map}).
 
+Note that while the \biber/\bibtex input site is not case sensitive when it comes to entry types and field names, the \latex side is case sensitive and uses the exact capitalisation from the data model. At the moment custom data fields are only supported in lowercase.

 Validation against the data model means that after mapping your data sources into the data model, \biber (using its \path{--validate_datamodel} option) can check:
