Shared tenancy classes in a service model architecture

A method for modifying objects with shared tenancy classes, comprising:

• receiving a request to modify an instance of an object of an object tree, wherein the object tree comprises objects designated as one of a tenanted class, a non-tenanted class, and a mixed-tenanted class, wherein the tenanted class comprises tenant data and allows user modification of the tenant data, wherein the non-tenanted class comprises non-tenanted data and does not allow user modification of the non-tenanted data, and wherein the mixed-tenanted class comprises non-tenanted data and allows user modification of the non-tenanted data;
• retrieving the instance of the object;
• determining, using a processor, whether class of the object is the tenanted class, the non-tenanted class, or the mixed-tenanted class;
• in response to determining that the class of the object is the mixed-tenanted class, determining whether the instance of the object is a tenanted instance of a mixed-tenanted object or a non-tenanted instance of the mixed-tenanted object, wherein the tenanted instance of the mixed-tenanted object is associated with a tenant;
• in response to determining that the instance of the object is the tenanted instance of the mixed-tenanted object:
• discarding the tenanted instance of the mixed-tenanted object in response to determining that the request is not associated with the tenant;
• and
• returning the tenanted instance of the mixed-tenanted object in response to determining that the request is associated with the tenant, wherein returning the tenanted instance of the mixed-tenanted object comprises modifying, based at least in part on the request, the tenanted instance of the mixed-tenanted object to obtain a modified tenanted instance of the mixed-tenanted object;
• and
• in response to determining that the instance of the object is the non-tenanted instance of the mixed-tenanted object, returning the non-tenanted instance of the mixed-tenanted object, wherein returning the non-tenanted instance of the mixed-tenanted object comprises creating a child instance of the non-tenanted instance of the mixed-tenanted object, wherein the child instance includes modifications to the non-tenanted instance of the mixed-tenanted object based at least in part on the request.

A computer program product for modifying objects with shared tenancy classes, the computer program product comprising a non-transitory computer readable medium and comprising computer instructions for:

• receiving a request to modify an instance of an object of an object tree, wherein the object tree comprises objects designated as one of a tenanted class, a non-tenanted class, and a mixed-tenanted class, wherein the tenanted class comprises tenant data and allows user modification of the tenant data, wherein the non-tenanted class comprises non-tenanted data and does not allow user modification of the non-tenanted data, and wherein the mixed-tenanted class comprises non-tenanted data and allows user modification of the non-tenanted data;
• retrieving the instance of the object;
• determining, using a hardware processor, whether a class of the object is the tenanted class the non-tenanted class or the mixed-tenanted class;
• in response to determining that the class of the object is the mixed-tenanted class, determining whether the instance of the object is a tenanted instance of a mixed-tenanted object or a non-tenanted instance of the mixed-tenanted object, wherein the tenanted instance of the mixed-tenanted object is associated with a tenant;
• in response to determining that the instance of the object is the tenanted instance of the mixed-tenanted object:
• discarding the tenanted instance of the mixed-tenanted object in response to determining that the request is not associated with the tenant;
• and
• returning the tenanted instance of the mixed-tenanted object in response to determining that the request is associated with the tenant, wherein returning the tenanted instance of the mixed-tenanted object comprises modifying, based at least in part on the request, the tenanted instance of the mixed-tenanted object to obtain a modified tenanted instance of the mixed-tenanted object;
• and
• in response to determining that the instance of the object is the non-tenanted instance of the mixed-tenanted object, returning the non-tenanted instance of the mixed-tenanted object, wherein returning the non-tenanted instance of the mixed-tenanted object comprises creating a child instance of the non-tenanted instance of the mixed-tenanted object, wherein the child instance includes modifications to the non-tenanted instance of the mixed-tenanted object based at least in part on the request.
