Classification of Everyday Living (2018)


For the past 3 years or so I have been actively involved in developing the Classification of Everyday Living Open Standard with the OASIS organisation. The Committee Specification for this standard has just been published (HERE).  

The Objective of the standard is as follows:

The COEL Specification provides a clear and robust framework for implementing a distributed system capable of capturing data relating to an individual as discrete events. It facilitates a privacy-by-design approach for personalised digital services, IoT applications where devices are collecting information
about identifiable individuals and the coding of behavioural attributes in identity solutions. The COEL Specification contains an extensive and detailed taxonomy of human behaviour. The taxonomy allows data from different systems to be encoded in a common format, preserving the meaning of the data across different applications. This ability to integrate universally at the data level, rather than just the technology level, is known as semantic harmonisation and provides full data portability. The communication protocols needed to support system interoperability across a wide range of implementations are also included. Central to the specification is the separation of static and dynamic personal data. Static data are those pieces of information about an individual that do not change or change very slowly or infrequently which are often used as direct identifiers. Dynamic data are those that describe the sequence of behaviours of an individual over time. This separation of data types provides many advantages for both privacy and security; it is known as pseudonymisation. The COEL Specification provides the means to achieve this separation of data as it is collected rather than as a later operation (pseudonymisation at source).
