<div>Hi Christiana,</div><div> </div><div>If by naming conventions you mean what we have named elements and attributes, I'd say we don't currently have many formal rules. These are the general ones we follow, at least in DDI-L:</div>
<div> </div><div>Words in object names are spelled out</div><div> </div><div>elements: upper CamelCase</div><div>attributes: lower camelCase</div><div> </div><div>The following element types follow the convention of XxxxTerm where Xxxx is unique to the applied use and Term refers to the type (i.e., ReferenceType) or genre (i.e., XxxxGroup)</div>
<div> </div><div>XxxxReference - Xxxx generally refers to the type of object being referenced</div><div>XxxxName - Xxxx is specific to the parent element type</div><div>XxxxGroup - Xxxx is specific to the parent scheme type</div>
<div>XxxxScheme - Xxxx is specific to the object type(s) in the scheme</div><div>XxxxDomain</div><div>XxxxRepresentation</div><div> </div><div>In preparing 3.2 we reviewed for consistency and imposed the following rules:</div>
<div> </div><div>An element name should appear in only one namespace</div><div>Attributes that occur in multiple locations (i.e., type) should perform the same role in each location</div><div> </div><div>The actual terms selected are not as generic as they could/should be. Some are carryovers from DDI-C, others reflect the questionnaire centric, social science centric history of early DDI. For example "DataCollection" should be interpreted as "DataCapture", the ControlConstruct which captures questionnaire flow can also capture a sequence of processes used to capture data from registries or from instruments capturing environmental, biomedical or other data. These issues are some that are being addressed as we look towards where DDI is moving in the future. </div>
<div> </div><div>If this does not address your question or you need additional information let me know and I will try to provide additional detail.</div><div> </div><div>Wendy Thomas</div><div>TIC</div><div> </div><div> </div>
