We would encourage groups that define tabular data formats to also define a mapping into the annotated tabular data model defined in this document. This specification does not define any formats for embedding metadata within CSV files, aside from the titles of columns in the header row which is defined in CSV. Many files containing tabular data embed metadata, for example in lines before the header row of an otherwise standard CSV document. around encoding and line endings) and contribute to its discussions about moving CSV to the Standards track. The working group's expectation is that future suggestions to refine RFC 4180 will be relayed to the IETF (e.g. This definition of CSV used in this document is based on IETF's which is an Informational RFC. Locating Metadata), though it also specifies an underlying model for tabular data and is therefore a basis for the other chartered Recommendations. This document aims to primarily satisfy the "Access methods for CSV Metadata" recommendation (see section 5. The CSV on the Web Working Group was chartered to produce a recommendation "Access methods for CSV Metadata" as well as recommendations for "Metadata vocabulary for CSV data" and "Mapping mechanism to transforming CSV into various formats (e.g., RDF, JSON, or XML)".

This section describes the status of this document at the time of its publication.
Note, however, that applications may have other means to create annotated tables, e.g., through some application specific API-s this model does not depend on the specificities described in.
The standard syntax for that metadata is defined in. This specification defines how implementations should locate that metadata, given a file containing tabular data. It also contains some non-normative guidance for publishing tabular data as CSV and how that maps into the tabular data model.Īn annotated model of tabular data can be supplemented by separate metadata about the table. This document outlines a data model, or infoset, for tabular data and metadata about that tabular data that can be used as a basis for validation, display, or creating other formats. Tabular data is routinely transferred on the web in a variety of formats, including variants on CSV, tab-delimited files, fixed field formats, spreadsheets, HTML tables, and SQL dumps. The English version of this specification is the only normative version.
