ENVEHS › Format and conventions used for OECD Harmonised Templates
An OECD Harmonised Template provides predefined fields, picklist values and freetext prompts related to a given endpoint that are considered necessary to summarise a study. In this context, an endpoint is an information requirement or data point with regard to the physico-chemical properties of the substance, environmental fate and behaviour, ecotoxicological information, toxicological information and specific information (e.g. residues in food and feedingstuffs) according to a given chemical programme.
Each template is structured into five main parts, which feature a number of data entry fields that are common to (almost) all templates and are therefore called "generic" elements. These include:
The generic field "Guideline" is not a generic field in a strict sense, since endpoint-specific picklists are provided.
As an exception to the rule, the generic part MATERIALS AND METHODS is not provided in the template no. 88 Effectiveness against target organisms and intended uses - general information.
In addition to generic fields, endpoint-specific data entry fields are available, the number of which varying from none or only a few up to many, depending on the degree of structure required for a given endpoint. For example, template no. 40. Additional information on environmental fate and behaviour provides only generic fields as no specific fields are needed here. On the other hand, many specific fields are provided in template no. 41. Short-term toxicity to fish.
In the first version of OECD Harmonised Templates, all generic data entry fields were compiled in a separate template which was referred to in the endpoint-specific templates. In the updated templates presented with this document, all generic fields are integrated except for fields subsumed under ADMINISTRATIVE DATA, which are described only once and referenced from each template by means of hyperlinks.
It should be noted that, for technical reasons, the naming conventions used for the XML schema of the fields subsumed under ADMINISTRATIVE DATA or ANNOTATIONS are somewhat different from those used for all other fields.
The format and conventions used for the updated OECD Harmonised Templates is described in the following subchapters, which can be seen as seven columns constituting each template.
