Technical standards reusability is the characteristic of a dataset to be stored in a standard which allows maximum reuse with minimum cost. This happens when the standard is open and there are free tools that implement it in order to retrieve the information. Qualified distinction is made based on the available documentation explaining how to determine the contents or the relevant ontology for semantic data. Every level is weighted in order to provide a fair comparison.
| Description |
% weight
|
| Level 1. Closed standard. Data sources in this level are released on proprietary standards, or in open formats but not suitable for reutilisation (i.e. image formats for text). The definition of open standard can be found in national level legislation.I.e. xls, pdf image, doc, shp, etc. |
10
|
| Level 2. Open standard. Data sources in this level are published on open standards but as individual files.i.e. csv, txt, odb, odt, ods, etc. |
25
|
| Level 3. Open standard with explanatory documentation. Data sources in this level include those which release information as open standards in individual files but showing available explanatory information about the contents of the files. i.e. csv, odb, odt, ods, etc. with additional information about the structure of the fields inside the file, size, data type, range of registers of the file. |
50
|
| Level 4. Open standard, individual access/metadata. Data sources in this level include those which includes metadata attached to any data. Additional information about the content of the data source is not available.i.e. rdf, json, xml (with meta-tags) without additional instructions |
75
|
| Level 5. Open standard with associated metadata and explanatory material. Data sources in this level include those which release information attached with the metadata, and additional information about the content of the data source is available. i.e. ontology.I.e. rdf with additional documentation |
