+Apache Arrow includes a cross-language, platform-independent in-memory
+columnar format allowing zero-copy data sharing and transfer between
+heterogenous runtimes and applications.
+
+The easiest way to use the Arrow columnar format has always been to depend
+on one of the concrete implementations developed by the Apache Arrow community.
+The project codebase contains libraries for 11 different programming languages
+so far, and will likely grow to include more languages in the future.
+
+However, some projects may wish to import and export the Arrow columnar format
+without taking on a new library dependency, such as the Arrow C++ library.
+We have therefore designed an alternative which exchanges data at the C level,
+conforming to a simple data definition. The C data interface carries no
dependencies
