The CSV on the Web Working Group has published 3 Group Notes:

• CSV on the Web: Use Cases and Requirements: A large percentage of the data published on the Web is tabular data, commonly published as comma separated values (CSV) files. The CSV on the Web Working Group aim is to specify technologies that provide greater interoperability for data dependent applications on the Web when working with tabular datasets comprising single or multiple files using CSV, or similar, format. This document lists the use cases compiled by the Working Group that are considered representative of how tabular data is commonly used within data dependent applications.
• Embedding Tabular Metadata in HTML: The Model for Tabular Data and Metadata on the Web describes mechanisms for extracting metadata from CSV documents starting with either a tabular data file, or a metadata description. In the case of starting with a CSV document, a procedure is followed to locate metadata describing that CSV. Alternatively, processing may begin with a metadata file directly, which references the tabular data file(s). However, in some cases, it is preferred to publish datasets using HTML rather than starting with either CSV or metadata files.
• CSV on the Web: A Primer: CSV is one of the most popular formats for publishing data on the web. It is concise, easy to understand by both humans and computers, and aligns nicely to the tabular nature of most data. The CSV on the Web Working Group has developed standard ways to express useful metadata about CSV files and other kinds of tabular data. This primer takes you through the ways in which these standards work together.
