I would like to know what standard(s) may exist for formatting log data from sensors that record information such as:
- acceleration vector
- magnetic field vector
- location vector (ex: GPS)
I have been an end-user of SCADA software products which record various data fields for each stream of log data it receives into a MySQL database. However, I have never looked into determining how exactly that data was stored. I would like to know if there exists an industry consensus standard for storing sensor data that facilitates information interchange. For example, the Internet Engineering Task Force (IETF) publishes documents called "RFCs" for the purpose of standardizing implementations of commonly used protocols like IMAP (email), TLS (secure web browsing).
For example, such a standard might indicate to me the best practices for:
- formatting units of measurement (ex:
- formatting of timestamps of each measurement (ex: ISO-8601)
- file format type (CSV files vs. SQL database)
- delimiters for measurement data (ex:
- indicating origin and license of data (ex: end device owner/operator, equipment tag number, CC RDFa tags)
- encrypting measurements (esp. in a way compatible with sudden power-loss, ex: DTLS)
While researching this question I noticed that the IETF says the Internet of Things (IoT) is a topic of study for several of its working groups. Its definition of IoT is
The Internet of Things is the network of physical objects or "things" embedded with electronics, software, sensors, actuators, and connectivity to enable objects to exchange data with the manufacturer, operator and/or other connected devices.
However, I did not find any IETF standards document describing standard methods for storing log data. Is there an ISA standard covering methods for logging data? I really like their ISA 5.1 standard for P&ID symbols, "Instrumentation Symbols and Identification".
Thank you for any direction you may provide.
