 * Have a completely specified format for the `TreeStore` and `DictStore`.  The format should allow to have containers either in memory or on disk.  Also, it should allow a sparse or contiguous storage.  The user will be able to specify these properties by following the same conventions than for NDArray objects (alas, `urlpath` and `contiguous` params).
 
-    * New `.save()` and `.to_cframe()` methods should be implemented to convert from in-memory representations to on disk and viceversa.
+    * New `.save()` and `.to_cframe()` methods should be implemented to convert from in-memory representations to on disk and vice-versa.
     * The format for `TreeStore` and `DictStore` will initially be defined at Python level, and documented only in the Python-Blosc2 repository.  An implementation in the C library is desirable, but not mandatory at this time.
 
 * A new `Table` object should be implemented based on the `TreeStore` class (a subclass?), with a label ('table'?) in metalayers indicating that the contents of the tree can be interpreted as regular table.  As `TreeStore` is hierarchical, a subtree can also be interpreted as a `Table` if there a label in the metalayer of the subtree (or group in HDF5 parlance); that can lead to tables than can have different subtables embedded.  It is not clear yet if should impose the same number of rows for all the columns.
