Heiko,
We had a version of this working in a heavily-customized GN for a while: all search results were programatically added to the OpenLayers LayerSwitcher (layers w/ services would then render directly, layers without live links rendered as a footprint).
We were trying to avoid additional windows at that time, but it could easily go into a new window instead. The code is still around if you want it: https://code.lib.purdue.edu/trac/gis/pugo/browser/trunk
Of course we're one of the groups that shortly thereafter abandoned the native GN UI, which freed us up to do a richer version of all of this: we render directly to OpenLayers from the search results (services and/or footprints), but we also have a little, what, "sidecart" (?) where users can drag layers they're interested in saving as citations or just looking at more closely together (the saving as citations part is not yet coded, but we're preparing). Those can of course be rendered/footprinted on OL at any time. With a reasonable amount of work, this cart thing could probably be put into the native GN UI, but for all the reasons Soroka has mentioned we just jumped ship.

Hello,
yes, the shopping cart facility is quite the same. The workflow would be: Search for metadata => Add results to MapViewer (= shopping basket) => Open MapViewer (in a separate window). Though our project is non-commercial... but would this be possible in GN?

Not to worry-- this discussion (providing different front ends to GN) has been going on in this list for some time. I think it is a healthy discussion. It shows how broad GN's user community is.
May I ask if you are proposing a sort of "shopping cart" notion? In other words, a facility that would allow patrons to gather up layers and featuresets into some kind of queue and then display them in an OpenLayers-based editor, perhaps in a separate viewing window or the like?

Hi,
sorry, it was not my intention to raise up a discussion. For me as a complete user, the excellent functionalities of GN concerning metadata editing, search, harvesting etc. are out of question. Also the embedded Intermap viewer is powerful for viewing and performing basic feature info queries and setting up styles, adding wms services etc. But in our recent project, the requirements to the map viewer will go beyond the capabilities of Intermap, (display in different CRS, editing features in the viewer etc.).
So my simple idea at the moment is: If I have searched for some metadata and have received the results, I can load the data into Intermap using the Interactive map function (OGC web map service 1.1.1 in the OnLine resource section). Would it be possible to change this function into something like "Add Data to OpenLayers", so I can choose several datasets to be added into OpenLayers first and then switch to OpenLayers for further analysis? And what would this mean for me regarding effort and time to spend, and is it worth it, if it is planned to integrate OpenLayers into GN in the near future?
So any suggestions on this problem and information about scheduled new releases of GN with OL are highly welcome.
Regards,
Heiko

Thanks! I understand your motivations and encourage the work you do! I just wanted to avoid getting a perception out on the mailing list that does not reflect how most people do use GeoNetwork at present

We have no disagreement-- my comment was poorly worded. What I meant was that most groups that have decided to create a substantially new interface have decided to completely replace the out-of-the-box one, as opposed to working within the XSLT and JavaScript that is provided.
This is for reasons that offer no criticism of the interface; it's good engineering to avoid setting yourself up to continually be remerging complex XSLT and JavaScript every time a new GN version is released. Also, it permits of using a framework besides Jeeves, which some groups may prefer. (E.g. we used Sinatra.)

Hi,
Even though I'm very much in favor of progressive development of the GUI, I think that the statement below is a bit bold... There are for sure people that have developed their own GN discovery interfaces, but to claim that "most groups have decided to simply replace the entire GN discovery section with something else" is maybe exaggerating a little, or do you really have stats to support this? It sounds like the default GUI is worth nothing, which I personally don't agree with Many people are happy with general cosmetic changes to the default GUI as far as I know, while some take the effort to develop alternative GUI solutions.
Cheers,
Jeroen
