Data format and set of tools for working with relational data.
Relational pipes are an open data format designed for streaming structured data between two processes. Simultaneously with the format specification, we are also developing a reference implementation (libraries and tools) as a free software.
The tools are 1) Input filters that converts other formats (e.g. CSV, XML, fstab, filesystem…) to the relational format, 2) Transformations that allows filtering and modifications (of both content and structure) of relational data, 3) Output filters that converts relational data to other formats (e.g. CSV, XML, null-byte separated values)
Transformations can be simple (like grep or cut with regular expressions) or complex and powerful – using GNU Guile expressions. SQL, AWK and Python transformations are planned for further releases.
