[EP-tech] doctype views with monograph-type and pres_type

Hi Tomasz

	This seemed complicated, and I did some fiddling around with browse menu render functions, but as I was doing it, I realised that I was replicating a subject tree browse view.

	1) Create a subject tree representing all types and subtypes.  For your subject IDs, use <type>_<subtype>. (https://wiki.eprints.org/w/Training_Video:Subject_Trees <https://wiki.eprints.org/w/Training_Video:Subject_Trees>).  Configuration would look something like:

	mongraph_technical_report:Technical Report:monograph:1

	It?s essential that the IDs in the subject tree exactly match the type/subtypes of the items.

	2) Create an automatic field that stores the type as the subject ID node on that tree (https://wiki.eprints.org/w/Training_Video:Automatic_Fields <https://wiki.eprints.org/w/Training_Video:Automatic_Fields>)

	my $type = $eprint->value(?type?);
	$type_with_subtype = $type;

	if ($type eq ?monograph)
		$type_with_subtype .= ?_? . $eprint->value(?monograph_type?);


	$eprint->set_value(?type_with_subtype? , $type_with_subtype);

	3) Create a browse view based on the automatic field (this part is in the automatic fields video).

	4) you can then rearrange the subject tree if you like so that book appears under monograph.

	I suppose type should be a subject tree, but it?s probably a bad idea to deviate that far from eprints norms for such an important field.  The down-side of this approach is that you now have type configuration in two places.  If you update any types or subtypes, you need to remember to update your subject tree.  That?s scriptable, but that?s probably overkill.  Alternatively, you can use the browse view render menu override capability (see https://github.com/eprints/eprints/blob/3.3/lib/defaultcfg/cfg.d/views_render_menu_example.pl <https://github.com/eprints/eprints/blob/3.3/lib/defaultcfg/cfg.d/views_render_menu_example.pl>) but that will involve generating a DOM tree.

I presume you are controlling the available set options in the workflow depending on the item type selected?
