ExtendedAttributesMBS question

In macOS, I’m trying to read old OpenMeta tags so I can rewrite them as new Finder tags. Here’s how I’m trying to read them:

[code]Public Sub FillList(theFolder as folderitem)
Dim theFile As FolderItem
Dim c, i As Integer

c = theFolder.Count
For i = 1 To c
theFile = theFolder.TrueItem (i)
If theFile <> Nil Then
Dim userTagsOM As Variant = ExtendedAttributesMBS.GetAttribute (theFile, “com.apple.metadata:kMDItemOMUserTags”)
// in debugger, userTagsOM shows as object(count) with members names _variantString

  Break // see in debugger
End If


I don’t know how to parse the result of the getattribute function. The docs are unclear.

Please check TagNamesMBS and SetTagNamesMBS in folder item class.

I have and they work with today’s version of tags (which are _kMDItemUserTags), but I’m trying to read the original OpenMeta attribute com.apple.metadata:kMDItemOMUserTags that Apple used when tags were introduced.

In my above code GettAttribute is returning an object array containing an item for each kMDItemOMUserTags.

The question is how can I read the values of this object array? Is it a pair, or collection, or plain string array? I keep tripping over my feet trying to read it and am just looking to be pointed in the right direction.

com.apple.metadata:kMDItemOMUserTags is stored as binary plist.

For com.apple.metadata:_kMDItemUserTags you can use our ExtendedAttributesMBS functions to read directly:

[code]Dim f As FolderItem = SpecialFolder.Desktop.Child(“test.eml”)
// query attribute
Dim v As Variant = ExtendedAttributesMBS.GetAttribute(f, “com.apple.metadata:_kMDItemUserTags”)

// plugin converts it to XOjo data types with variants
If v <> Nil Then
// tags should be an array of Variant with strings
Dim a() As Variant = v

For Each s As String In a
MsgBox s
End If[/code]

As far as I read you can use the same code for “com.apple.metadata:kMDItemOMUserTags”.

Thanks Christian. I ended up just using an array directly, like so:

Dim userTagsOM() As Variant = ExtendedAttributesMBS.GetAttribute (theFile, "com.apple.metadata:kMDItemOMUserTags")

This cleanly populates the variant array with the OpenMeta tags (and works with new tags as you mentioned).
