Trace Windows, the obvious analysis pattern that was always implicit, is added now due to the proliferation of stream processing nowadays. However, it captures not only horizontal windows but vertical ones, similar to subspaces if we consider messages as vectors. Both types of windows can be combined. This is illustrated in the following diagram:

Most of trace and log analysis pattern illustrations using Dia|gram language are of these two general forms:
Although the first form represents typical ETW trace attributes, the analysis pattern descriptions are usually independent of attribute name semantics. It, therefore, makes sense to generalize such forms into the following Trace Schema forms, with ATIDs for Adjoint Threads of Activity for the first form, and with FIDs for Features of Activity for the second form:
Such Trace Schemas are useful for various trace and log joins other than Trace Mask.
