=== Add metadata to image collections ===

Follow these instructions if you have a collection of images and each image has metadata and you want the collection to be displayed like [[http://echo.mpiwg-berlin.mpg.de/content/religion/bulgaria/folk_images1?|this]].

  - If you don't have a filemaker database which contains the metadata, create one.\\ In this database there has to be a field which contains the name of the image file and then a field for each metadata (e.g. painter, description, ...).
  - Create a SQL database out of your filemaker database (see [[fm2sql|here]] for more information).
  - Upload the images to the foxridge (see [[image_quality|here]] for more information about the quality of images). You can have more than one folder, e. g. if you want your images to be sorted by theme, painter ...
  - Go to the [[basic_terms|Zope Management Interface]] of ECHO (see [[zope_management|here]] for more information) and go to the collection/group the new image collection shall belong to. You can add the new image collection to an existing collection or you can [[create_echo_collection|create a new collection]] for that.
  - Parallel to or in the collection your images shall belong to, create a ''Psycopg_database_connection'' (see [[Create_a_new_object|here]] how to add a new object). In the property list you can leave almost everything like it is, just fill in the "Connection String":\\ ''dbname=databasename user=username password=password host=servername''\\ Ask the one who set up the SQL database for database name, user name, password and host.\\ If there is more than one ''Psycopg_database_connection'' object you may have to change the id. You don't have to, but you can change the title as well to make the handling of the objects more easier. 
  - Now, again, go to the collection your images shall belong to. Add an ''ImageCollection MD'' object.
  - Fill in the fields //Folder Path// and //Viewerpath Path//.\\ The //Folder Path// is the relative path of the folder the images are in on the foxridge. The //Viewerpath Path// is the same as the //Folder Path// but without the first two folders.\\ For example: You have a folder named "image_folder" and the path on the foxridge is "/mpiwg/online/permanent/test/image_folder". The //Folder Path// of this folder is "/mpiwg/online/permanent/test/image_folder", the //Viewerpath Path// is "permanent/test/image_folder".\\ {{collectionmd.jpg}}\\ **Attention:** When you mount the foxridge via the Finder ("Go to" >> "Connect to Server...") you got one folder named online_permanent or online_experimental, but in a path deklaration you have to split this into two folders (online/permanent or online/experimental).
  - When you click on the tab //ZSQLExtend// you can choose a database connector. If there is only one ''Psycopg_database_connection'' object, you shouldn't have to change the //Connection Id//. Otherwise you can choose a database connector from the pulldown menu.\\ {{zsqlextend.jpg}}  {{connection.jpg}}
  - In the ''ImageCollection MD'' there have to be two templates: //overview.html// and //thumb.html//\\ You can copy them from the folder //templates// which is located in the [[http://echo.mpiwg-berlin.mpg.de/manage|root folder]] of echo.\\ See [[overview_thumb|here]] for more information how to change these templates.
  - Now, the next step is to bring in the images. For doing that, make sure that the url of the browser is the url of the ''ImageCollection MD''.\\ {{import.jpg}}\\ Then replace "manage" with "ImportStructure". Press Enter.\\ There should be one or more ''ImageDigilib'' objects, now. 
  - Your image collection is finished now. If you click on the tab //View// you can see your images in the ECHO website.
  - What remains to do is to link to the image collection. Add a ''[[echo_links|ECHO_link]]'' object to the collection where your image collection belongs to. In the field //Link// type in the name of your image collection. When you have added the ''ECHO_link'' object the link should appear in the ECHO website. See [[change_link_layout|here]] if you want to know how to change the layout of the link. If you want the ''ECHO_link'' object to be displayed like a resource copy the //link_template// in the template folder (in the root folder) to the collection.
  - If you have uploaded more than one folder in step 3, go back to step 6 for more image collections.
