    1010Finally, we will assume that all the time series will be referenced by the daily-resolution (UoM=days ['''d''']) [http://kahlua.eecs.jacobs-university.de:8080/def/crs/OGC/0.1/ANSI-Date ANSI-Date] CRS along the temporal dimension, which (by default) has a '''`t`''' positive-onwards axis.
     11By default the ''composition order'' of spatiotemporal CRSs here is first space, then time; this however is not required at all.

    1213NB. The axes labels expressed in the geometric domain of a coverage are the labels of the '''coverage''' axes, which here will be labelled as increasing numbers `(0, 1, 2, ...)`, by default. Indeed, they are independent from the axes labels of its '''CRS''', which are instead used in the WCS ''!GetCoverage'' requests.

     29Due to the high number of possible cases, hereinafter we propose a first main table for global view which puts purely-spatial types of topology per row, which can then be repeated, or evolve, in time with or without regular time steps (columns).[[BR]]
    2930Each cell then links to a dedicated subsection with the GML descriptions (assume default namespace is "`gml`").

    4659This section covers time series of point observations with no spatial reference (or where the spatial reference was not considered relevant): in this case the only distinction is whether there is a regular time step between observations, or not. In its degenerate case, the series turns to a [#a1a single point].

Several sub-cases are covered, depending on the regular/irregular spacing between the points, the alignment of this line to one of the axes of the CRS, and the dimensionality of the encompassing space (i.e. the dimensionality of the CRS).
