Hi all,

Is there a way to get a list of Tag History providers in Perspective? For instance, using something like:

```python
def getDatabaseTagList():
	parentPath = '[System]Gateway/Database'
	results = system.tag.browse(parentPath)
	obj = [{'value':idx, 'label':results[idx]['name']} for idx, result in enumerate(results.getResults())]
	return obj

```

Many of the names listed do not have historical tags associated and or are not recognized as a Historical Tag Provider.

I am using this code in the Script Console and manually going through the names found on the Developer GW:

```python
path='histprov:Sim_Coater:/drv:Ignition-TWCGHMIDT01:default'

def one(path):
	tag_paths = []
	results = system.tag.browseHistoricalTags(path).getResults()
	print(system.tag.browseHistoricalTags(path).getReturnedSize())
	for result in results:
		strPath = result.getPath()
		print(strPath)
		if result.hasChildren():
			one(strPath)

one(path)

```

Most of them do have tags, and many throw a `Nonetype object is not iterable`.  
What I am looking for is a way to create a dictionary object for a dropdown, so I can select the Provider, and run some cleanup scripts on the historical tags.

Thanks

Recalling that `system.tag.browse()` (no arguments) returns all realtime tag providers I tried `system.tag.browseHistoricalTags()` (no arguments) and it does appear to return all historical tag providers.
