Do annotations on a referring tier with the stereotype ‘included in’ or ‘time subdivision’ have their own time code (independent of the time code of the parent tier)? Moreover, is the information on annotations (e.g., content and time code) with the stereotype ‘symbolic association’ separable from that of the parent tier in the final (exported) data? In other words, if I would like to extract data only from the referring tier, would that be possible?

Thank you in advance!

The annotations on an included in tier have their own time codes (which are always forced inside the boundaries of the parent annotation).

The annotations on a time subdivision tier also have their own time codes, except for the first child annotation (of each parent annotation), which shares its start time with the start time of the parent, and the last child annotation, which shares its end time with the end time of the parent annotation. The child annotations form a chain, where the end time code of one annotation is the start time of the next etc.

Any tier can be exported separately and independently (annotations on symbolic association tier inherit the time codes of the parent, time codes for annotations on symbolic subdivision tiers are calculated by interpolation). The content of annotations is always separable when exported.
