Description:
 def open_catalog(uri=None, **kwargs):
 """Create a Catalog object Can load YAML catalog files, connect to an intake server, or create any arbitrary Catalog subclass instance. In the general case, the user should supply ``driver=`` with a value from the plugins registry which has a container type of catalog. File locations can generally be remote, if specifying a URL protocol. The default behaviour if not specifying the driver is as follows: - if ``uri`` is a a single string ending in "yml" or "yaml", open it as a catalog file - if ``uri`` is a list of strings, a string containing a glob character ("*") or a string not ending in "y(a)ml", open as a set of catalog files. In the latter case, assume it is a directory. - if ``uri`` beings with protocol ``"intake:"``, connect to a remote Intake server - otherwise, create a base Catalog object without entries. Parameters uri: str Designator for the location of the catalog. kwargs: passed to subclass instance, see documentation of the individual catalog classes. For example, ``yaml_files_cat`` (when specifying multiple uris or a glob string) takes the additional parameter ``flatten=True|False``, specifying whether all data sources are merged in a single namespace, or each file becomes a sub-catalog.
