Olog is implemented as a REST style web service. Its intended use is as an electronic logbook for accelerator operations
A Logbook is a critical element used in order to record information acquired over time. This information usually consists of data sets, ongoing activities, and events occurring; with the main purpose of having a history of what was known at a certain time. This project will create a new logbook application, with a flexible plugin-based framework, that can meet future requirements through the use of additional plugins.
Olog tries to overcome this limitation by implementing a generic log service, which applications can query for a list of logs that match certain conditions, such as physical functionality or location.
Each log entry consists of a log, an arbitrary set of properties (name-value pairs), and an arbitrary set of tags (names).
An application sends an HTTP query to the service, specifying an expression that references tags, properties and their values, or log id. The service returns a list of matching logs with their properties and tags, as an XML or JSON document.
Other methods allow manipulation of log entries: create, update, add properties or tags, delete.
