Records
A record represents a set of attributes and their corresponding
values of an artifact. For example, the following record may represent
that a person named Tore has the income 100000:
{"name":"Tore", "income":100000}
Other commonly used terms for records are JSON objects, property lists, or dictionaries.
Let's assign the record above to a variable :t:
set :t = {"name":"Tore", "income":100000};
:t
An attribute a in a record r can be accessed using the r[a] notation, for example:
:t["name"]
JSON records is a common data format in external data sources and streams.
