Information is stimuli that has meaning in some context for its receiver. When information is entered into and stored in a computer, it is generally referred to as data. After processing (such as formatting and printing), output data can again be perceived as information.

When information is packaged or used for understanding or doing something, it is known as knowledge.

Information is always about something, and we can use the word 'entity' for that something. This is because all 3 definitions below, taken from dictionaries, are OK.

Entity (Plural Entities)

1. something that has a real existence;

2. something that has a separate existence

3. being or existence, especially when considered as distinct, independent, or self-contained.

By calling the information about the entities for 'attributes', It follows that “Information is Attributes about entities”, and “Attributes about entities is Information. 

This is because in a digital world it works both ways.

There are two types of attributes.

A. Those that can be measured using some units of measurements, we have agreed on, and

B. those that can NOT be measured, but are “assigned” by people to entities.

If we wish to store information we need to have an identifier for the entity that has the attributes, to be stored about it.
