Commonly used metadata

Items, or objects, stored in the Macrobond database are called 
entities. The most fundamental type of entity is the Time series, while some other types are Region, Release, Source, Index, and Security. All entities have unique 
names/identifiers.

All entities have metadata fields that describe them. These pieces of information come as a set of metadata
attributes
.

There are different types of attributes. Some can take its values only from a list of pre-defined values, while others allow more flexibility. Attributes come in different data types such as string, timestamp, boolean and integer. Entities can also function as meta data for other entities and in such cases act as regular attributes. An example of this is the Region attribute/entity.

Given the name of an attribute, you can use the Macrobond API to get more details.

Some metadata attributes are used just for descriptive purposes, to form series titles and to organize them, and these are prone to change as the organization of the database is changed.

Other metadata is used to describe properties of an entity. The below table lists the most common and useful
metadata attributes, divided into the entities they refer to:
