What are classifications?

Classifications provide a way to record descriptive information about the sources, nodes and relationships in your project:

While source and node classifications behave in a similar way, they are used for different purposes:

For more information, refer to About classifying sources or Classify nodes (set attribute values to record information).

Relationship Types are a special type of classification—they let you describe the nature of the relationship (development 'impacts' water quality). Refer to About relationships types for more information.

Working with source classifications

When you click on Source Classifications in Navigation View you will see the classifications that are available in your project:

If you cannot see any classifications, then you may want to:

Each classification has its own unique set of attributes. For example, if you expand the classification Newspaper Article you can see the attributes that are available for recording:
 

As you classify your sources, you can specify an 'attribute value' for each attribute:

Attribute Value
Reporter Benjamin Smith
Year 2010
Title Urgent Challenges of Climate Change

When you import data from a reference management tool, the sources are automatically classified and the attribute values are assigned.

When you click on Node Classifications in Navigation View, you will see the node classifications that are available in your project:

If you cannot see any classifications, then you may want to

Each node classification has its own unique set of attributes. For example, if you expand the classification Person you can see the attributes that are available for recording:

As you classify your nodes, you can specify an 'attribute value' for each attribute:

Attribute Value

What is a classification sheet?

When you have classified your sources or nodes, you can open a grid that displays the attributes for all items in a particular classification—this grid is called a classification sheet.

For example, you could open the Person classification sheet and see all the nodes in this classification. The nodes are displayed along with their attribute values—you can sort and filter the sources based on their attribute values (for example, age and sex). You can also update attribute values via the classification sheet.

Refer to About classification sheets for more information.

In Navigation View, under Classifications, there is a folder for relationship types—relationship types are a special type of classification.

Relationship types describe the nature of a relationship (node) that occurs in your project. For example, you could set up a relationship type married and another relationship type lives with.

Unlike other classifications, relationship types do not have attributes—when you create a relationship type you need only define the direction of the relationship (associative, one-way, or symmetrical).

Refer to About relationship types for more information
