Title types

Studies have a scientific (full or protocol) title, and some data objects, such as journal articles, also have explicit titles. In many cases either studies or data objects can also have alternative or additional titles. The system keeps these in the database so that they can be used in searches, and they are categorised using the title types listed in this table.

id	name	applies_to	description	source
16	Trial registry title	Study	Full scientific title, as quoted in a trial registry.	ECRIN
17	Protocol title	Study	Full scientific title, from a punlished protocol.	ECRIN
18	Other scientific title	Study	Full scientific title, not from the protocol or registry entry.	ECRIN
14	Acronym or Abbreviation	Study	As provided by study sponsors.	ECRIN
15	Public Title	Study	In contrast to the full scientific title, usually from a trial registry.	ECRIN
12	Subtitle	All	A subtitle provided by object creators or study sponsors.	DataCite
13	Translated Title	All	Used in conjunction with language code to indicate language translated into.	DataCite
19	Journal article title	Data Object	Full journal title, as listed in citation.	ECRIN
20	Unique data object title	Data Object	Use if the given name for the data object can be guaranteed to be unique.	ECRIN
21	Study short name :: object name	Data Object	Constructed using study short name to prefix a non unique name. If obvious from context study name can be omitted.	ECRIN
22	Study short name :: object type	Data Object	Constructed using study short name to prefix object's type. If obvious from context study name can be omitted.	ECRIN
23	Study scientific name :: object name	Data Object	Constructed using study full name to prefix a non unique name. If obvious from context study name can be omitted.	ECRIN
24	Study scientific name :: object type	Data Object	Constructed using study full name to prefix object's type. If obvious from context study name can be omitted.	ECRIN
25	Study registry ID :: object name	Data Object	Constructed using registry id to prefix a non unique name. If obvious from context study ID can be omitted.	ECRIN
26	Study registry ID :: object type	Data Object	Constructed using registry id to prefix object's type. If obvious from context study ID can be omitted.	ECRIN
90	Other Alternative Title	All	Any alternative title not described elsewhere.	DataCite
0	Not yet known	All	Dummy value supplied by default on entity creation.	ECRIN

In most cases (non journal) data object titles will have to be constructed as they will not possess a unique name. The preference should be to use the short study title as the prefix for the object's name or type, with the two separated by a double colon, e.g.
    The Biopsychosocial Burden of Prostate Biopsy :: CTG Registry entry, or
    Reducing Hippocampal Hyperactivity and Improving Cognition in Schizophrenia :: Protocol
Where this is not possible the scientific title can be used. If the scientific title is too long (e.g. longer than 200 characters) it may be more useful to use the study's primary registry id as a prefix instead.
In all three cases the context will often make it unnecessary to include the prefix. For example the display of linked data objects under a study heading would allow the study name prefix to be dropped.
