Legacy data format migration

One of the most rewarding aspects of our data research and processing schedules is when we are asked by interested data users to investigate the potential format migration of old “legacy” data, either binary or ASCII format, into current dissemination software formats. Some of this legacy data dates back to the 1950s and 1960s. This requires the composition of appropriate code and syntax to pick up the data and compile it into a format that is easier for the 21st century data user to work with. Provided the legacy dataset has readable documentation (often from scanned paper questionnaires or codebooks) to accompany the germany rcs data legacy data files, there is a very good likelihood that this format migration can be achieved. We do our best to research and improve the accompanying documentation and where feasible attempt as much value-added variable and response value labelling as possible. Hopefully the interested data user will find the new dissemination format dataset useful for their research, often leading to a succession of related legacy dataset requests.


We have a programme of legacy data format investigation, with the aim of migrating many legacy datasets forward, if possible. Some legacy datasets are the precursors to more familiar highly used Government data series. These old binary and ASCII data files are at present not very user-friendly for non-technical data users, not used to writing syntax and code. We are in the process of migrating forward the National Readership Surveys which are currently very popular with data users. Also, with the recent Scottish Referendum and the forthcoming EU Referendum in the UK, we are investigating old Common Market Referendum studies for possible format migration, as these studies from the 1970s and 1980s may well be useful to researchers. As each dataset is successfully processed to current Dissemination Information Packages and Archival Information Packages, these are flagged as newly available for interested researchers.
