A csvs dataset is a directory that contains plain text files in the “comma-separated value” format, or CSV. Any directory that contains a .csvs.csv file is a valid csvs dataset. Each CSV file represents a table with two columns and is called a “tablet”. The first column is a key, and the second column is a value. You can store records by appending lines to the tablets. To represent complex objects and connect the tablets to each other, specify the relationships between values in the schema file _-_.csv.
Here’s an example of the simplest csvs dataset that contains a record about visiting Japan in 2001.
# .csvs.csv csvs,0.0.2# _-_.csv event,date# event-date.csv visited-japan,2001-01-01
