With respect to the time dimension, attributes and metrics attached to an object in the Roadmap view or Life Cycle Management view can be considered in one of two modes: 

  • Without a time dimension, making it a timeless property, and in case of a metric, having timeless values.
  • With a time dimension, making it a timed property, and in case of a metric, having timed values.


The timeless value of a property or metric can be set independently of the timed values of the property or metric, and vice versa. So an attribute or metric can have a timeless value as well as timed values.

Adding timed values to an attribute or metric

To add timed values to an attribute or metric of an object in a timeline view, follow these steps:

  1. In the view, select the object, and then click  to open its properties form.

  2. For adding timed values to an attribute, click the Basic profile tab or another tab containing the attribute.

    For adding timed values to a metric, click the Metrics tab.

    In the example figure below, the metric we are adding timed values to, already has a timeless value attached.



  3. Put the attribute or metric in edit mode by clicking  or  to the left of the attribute or metric.



  4. In the control bar of the form, click  to show the time dimension in the properties form. The Date column appears and shows the start date and end date of the object's lifetime.

    If the start date and/or end date are not correct, change them first by clicking a date, and then selecting the desired date.



  5. Click to the right of the start date in the Value column, and in the window that pops up, type the first timed value for the attribute or metric.



  6. To add the next timed value, click  in the control bar of the Date column, select the start date for the next timed value, and type the value. Repeat this step for each timed value you want to add.


The end result is a list with start dates and associated values for the attribute or metric.



To hide the time dimension again after adding the timed values, just click  in the control bar. If the attribute or metric already had a timeless value attached, that value will be shown again.

Copying the timeline of an attribute or metric

It is possible to reuse an attribute or metric's timeline in another object's attribute or metric by copying a timeline and pasting it in the properties form of another object.

Copying and pasting timelines between attributes and metrics is only possible within the same view. You can copy from one attribute to another, or from one metric to another, but also from an attribute to a metric and vice versa. When copying a timeline, only the dates are included. The associated values are not copied.

Steps:

  1. Open the properties form of the object containing the attribute or metric with the timeline values.

  2. In the properties form, put the attribute or metric in edit mode by clicking  or  to the left of the attribute or metric.

    If the properties form does not show the timed values of the attribute or metric, click  to make them visible.

  3. In the control bar of the Date column, click  to copy the timeline.



  4. Open the properties form of the other object, and put the attribute or metric you want to copy the timeline to, in edit mode.

    If the properties form does not show the time dimension, click .

  5. In the control bar of the Date column, click  to paste the timeline.


As a result, the copied timeline is shown in the Date column of the other attribute or metric.



You can now set the associated values for the start dates by clicking the values in the Value column, and then adding the values.

Lifetime differences

If the lifetime of the object you are copying the timeline to, differs from the lifetime of the object you have copied the timeline from, the copied dates may be shown in red to indicate that they fall outside the timeline of the object. An example is shown below.


Object with timeline that does not fit the object's lifetime


To resolve this, you can either change the dates of the timeline to make them fit the object's lifetime, or change the object's lifetime date(s) to make them fit the timeline start and end date.
