You will want to create a reference type or adopt a ref type you don’t use with similar fields or create a new one from one of the unused types.
Is xy the company or an author? I searched for citing a Datasheet and found the following suggestions which aren’t necessarily how the DIN standards would do it, but I can’t read German and can’t find “Datasheet” with DIN descriptions.
Data Sheet in IEEE
[10] Texas Instruments, “High speed CMOS logic analog multiplexers/demultiplexers,” 74HC4051 datasheet, Nov. 1997 [Revised Sept. 2002].
and this from an engineering librarian, on how to list chemical MSDS datasheets (to which your style would add the bibliography number?)
Dimethyl Sulfoxide; MSDS No. D7120 [Online]; Mallinckrodt Baker: Phippsburg, NJ,
May 25, 2005, http://www.jtbaker.com/msds/englishhtml/d7120.htm
(accessed July 20, 2007).
for example, you could start with Online Media (snippet shown in first attachment), Webpage, or Newspaper if you don’t already use one of those.
Then you need to add that template to your bibliography and fill it with the information you want to display in the order you described (showed two options in snippet 2 attached. For Online Media - I tried to follow your example. For Online Database - i tried to mirror the Data Sheet in IEEE above example.
The actual modified style is also attached, which you could input your info into either Online Media or Online Database and see if it works?
