![]() ![]() If a direct equivalent doesn't exist, how have you managed to work with complex metadata when using these formats? Do you manually perform data type conversion, formatting, and carry the metadata around? Interestingly, I've noticed it's often easier to convert data to the SAV/sas7bdat/sas7bcat formats than it is to convert from them.Īre there any fully-featured, open-source, file-based formats for tabular data that are language-agnostic and capable of storing complex metadata like SPSS's SAV or SAS's sas7bdat/sas7bcat formats? I'm aware of libraries like ReadStat, but I've experienced problems when reading files or encountered incorrect or poor conversions of complex data types, which then need to be corrected afterwards. ![]() To increase interoperability and efficiency within our group, I'm searching for an open-source, language-agnostic format with capabilities similar to the SAV/sas7bdat/sas7bcat formats, specifically the ability to store complex metadata. While these formats work well for those using SPSS or SAS, due to their comprehensive metadata handling capabilities (variable labels, value labels, missing value definitions, multiple response sets, etc.), they create significant challenges when trying to utilize other programming languages or tools for data analysis and manipulation. In my research group, a substantial amount of data is stored in SPSS's SAV or SAS's sas7bdat/sas7bcat formats. ![]()
