摘 要：Originally designed as a RESTful protocol to expose reading data from simple instruments, we discuss theshifting role of sMAP as a common interchange format for timeseries data within a number of building projects.Due to the change in role and resulting widened set of use cases, we discuss where sMAP has fallen short anddesign modifications necessary to address them. Key contributions are identifying a set of features required for the broad applicability of a protocol for publishing time-series data, and a concrete proposal and implementationof our design grounded in a diverse set of use cases and real deployments.
