2. Binding app for Caliper ########################## Status ------ Approved Context ------- We need to decide some approach to encapsulate and structure the Caliper events. We have the following options for binding caliper events: - Make our own data structure to store a caliper event (e.g. a python dict) - Use IMS’ `caliper-python `__ library Decision -------- We will be using python dictionaries for processing and encapsulation of transformed events to keep things simple. Consequences ------------ Python dictionaries will be used for binding Caliper events. These events stored as python dictionaries can be converted into JSON later and sent to interested consumers. Rejected Alternatives --------------------- **Use IMS’ caliper-python library** The library under discussion is not published on `PyPI `__. We’d have to fork the repo and add its dependency on our app. Therefore we won’t be using this library.
