Item Types, Categories and Frames<\/h3>\n
When you define the schema, you can specify a \u2018description<\/em>\u2018 for all of these parts, including:<\/p>\n These descriptions are very useful to end users, because Cradle<\/em> will display them as tooltips<\/em> in the UI (User Interface). For example, when the user moves to set a category value, Cradle will display:<\/p>\n When a user moves into the heading for a frame, the UI will display the description of that frame as a tooltip.<\/p>\n A comment as to the purpose of the link rule can be added to the schema. This is a useful aide-m\u00e9moire to those editing the rules. However, if a certain action is prohibited by the rules, then the user is shown why.<\/p>\n In this example two rules have been set up, one to allow user Alan to modify sub-part to component links and another to prevent all users modifying the same link. Because of the top-down sequence of rule matching this has the effect of allowing only Alan to modify cross references of this type. The example shows Dewi trying to modify the link attributes between the Pump parent component and the Pump housing linked as a sub-component. The warning shows why this alteration was prevented. The text from the schema is shown in the dialog.<\/p>\n Within Cradle<\/em> item types can have a number of different categories<\/em>. Some item types may share the same categories<\/em>, others may use unique values.<\/p>\n The Group<\/em> field is available across the whole project. When the schema<\/em> contains a number of entries for the Group<\/em> field, these can be applied to any item type. If the project defines values for the Group<\/em>, selection is only from the defined list. If no pick-list is defined, it is simply a free-form text field, to use as the user wishes.<\/p>\n This example shows three types of assets, Capital, Inventory<\/em> and Liquid<\/em>. Some item types may only fall into one group<\/em>, in this example a physical bedroom<\/em> is going to be a capital asset<\/em>, the guest supplies<\/em> are liquid assets<\/em>. However, when it comes to fittings<\/em>, the light<\/em> is being grouped with the Capital assets<\/em> and the bed<\/em> and so on in the Inventory group<\/em>.<\/p>\n However you choose to use this cross item categorisation, the descriptions given to the group<\/em> show as tooltips when hovering over the group<\/em> field in a form<\/em>.<\/p>\n\n
