[a]This is an example of a blank node that is only used by one other node. It provides the org:OrganizationID object that links the Organization to an id that is provided by an external issuer. In this case, the identifier is a business number issued by the Canada Revenue Agency. If it were needed by other nodes, it would be better to assign it a 'blank node ID' and define it in its own context. [b]hasLegalName is a required field for all Organizations. Each Organization should have exactly one instance of this property, given as a string. See table for details. [c]This is NOT a blank node. This URI points to an indicator defined by AffordableHouse. It should have an associated definition available at this address. The id provided here can be referenced by other nodes in the graph. See 'forIndicator' in the IndicatorReport object below. [d]This property creates a link to the Indicator1 ('Length of Tenure') object defined above. [e]This blank node is a i72:Measure object nested in and belonging to the indicatorReport1 object. Through the above id link, this IndicatorReport connects a value of 75 to the 'percentage of TMs who have lived in Affordable House accommodation for more than 5 years.' indicator
