Temporal data with parallel xml format

Hello everyone,
Since Temporal dataset already consists of multiple data files, could it still be divided, or subdivided, into a number of pieces that supports parallel I/O. I learn that ParaView offer a way to write every timestep as a file series, however, does the dataset is still regarded as being “temporal”?

could it still be divided, or subdivided, into a number of pieces that supports parallel I/O

Yes

does the dataset is still regarded as being “ temporal ”?

Yes, when opened as a time-series.
