What data are made available?
Before being made available in any form, the data are anonymised to remove data that may identify an individual institution or individual person. Then the data file is made available 'as is'. We identify this as Level 1. It includes resolver redirect requests and those "lookup" requests where no institution is identified. It excludes the button requests as these identify an institution. It may be used by anybody for any purpose that they believe will be useful, such as for analysis or to create services for UK Higher and Further Education. The Level 2 data file contains data that have been further processed, i.e. all extraneous data are removed leaving only redirection data. EDINA uses these data as the basis of a prototype recommender service for UK HE and makes them available for others to use.
We distinguish three levels of data as follows:
| Level | What's this? | What has been processed? | Is it available? |
|---|---|---|---|
| 0 | Original log file Data | No processing (contains identifiable IP addresses and institutions) | No |
| 1 | Anonymised Data | IP addresses are encrypted using an algorithm and institutional identifiers are anonymised | Coming soon |
| 2 | Anonymised Redirect Data | A subset of the Level 1 data, containing only entries that redirect to a resolver | Yes |
