class Directory from TDataStd inherits Attribute from TDF

    	---Purpose: Associates a directory in the data framework with
    	-- a TDataStd_TagSource attribute.
    	-- You can create a new directory label and add
    	-- sub-directory or object labels to it,


uses Attribute       from TDF,
     Label           from TDF,
     GUID            from Standard,
     DataSet         from TDF,
     RelocationTable from TDF

    Find (myclass; current : Label from TDF; D : in out Directory from TDataStd)
    	---Purpose: Searches for a directory attribute on the label
    	-- current, or on one of the father labels of current.
    	-- If a directory attribute is found, true is returned,
    	-- and the attribute found is set as D.
    returns Boolean from Standard;

    New (myclass; label : Label from TDF)
    	---Purpose:  Creates  an  enpty   Directory attribute,  located  at
    	--          <label>. Raises if <label> has attribute
    returns Directory from TDataStd;
    
    AddDirectory (myclass; dir : Directory from TDataStd)
    	---Purpose:  Creates a new sub-label and sets the
    	-- sub-directory dir on that label. 
    returns Directory from TDataStd;

    MakeObjectLabel (myclass; dir : Directory from TDataStd)
    	---Purpose:  Makes new label and returns it to insert 
    	--           other object attributes (sketch,part...etc...) 
    returns Label from TDF;
