Problem
Sometimes the user wants to record his own information about a security. For example, he does a research for some shares and now wants to record them. Therefore, the user should be able to define additional private properties for a security. The property should support different data types; possibly also a formula for calculating a value.

Solution

• The user can define additional own properties for the information class securities, possibly also other information classes. Several different properties are possible for which a data type such as text, number, etc. are possible. Maybe for the securities depending on the asset class or the type of instrument the property should be assigned. For example, for a bond it would be the rating, for the share the assessment of a particular analyst and for an ETF the share of the USA.
• GT could also use this extension of the data schema with predefined properties. For example, a property for the bonds for the interest accrued so far since the last interest date. This property would then be for each user, of course.
