Discovering the features of a provider

Not wanting to upset the author, I'll not mention the exact provider, unless
the person recognizes my name and jumps in here...

Is there any way to figure out how a provider works? There is no
documentation for it. Seems get-itemproperty would be something to help me
get started, but I get this:

20> gci|%{get-itemproperty $_.name}
Get-ItemProperty : Cannot use interface. The IPropertyCmdletProvider
interface is not supported by this provider.
At line:1 char:23
+ gci|%{get-itemproperty <<<< $_.name}

I'm trying to figure out how I can add a new item along with its properties
to make it work properly.

Not sure if this will help

(get-psprovider function).helpfile will give you the help file associated
with the provider - replace function with your provider - may be some info in
there?

I'm not sure whether this will help your or not:

PS> cat Get-ProviderInterfaces.ps1
$hash=@{}
foreach ($p in Get-PsProvider)
{
foreach ($i in $p.ImplementingType.GetInterfaces())
{
$interface = $i.Name
if (!$hash.$interface)
{ $hash.$interface = @()
}
$hash.$interface += $p
}
}
$hash
PS> C:\ps\Get-ProviderInterfaces.ps1

Name Value

IContentCmdletProvider {Alias, Environment, FileSystem, Function,
Variable}
IDynamicPropertyCmdletProvider {Registry}
ISecurityDescriptorCmdletPr... {FileSystem, Registry}
IResourceSupplier {Alias, Environment, FileSystem, Function,
Registry, Variable...}
IPropertyCmdletProvider {FileSystem, Registry}
