Overall logic:
- Detect the page context:
- check if the page is main window (ignore)
- check if the page is collection splash (ignore)
- check if the page is a viewer
- get the image id and type, process it.
- check if the page is thumbnail page
- ignore small window
- check if metadata window is visisble. If so, get the image id from each
small window and process them
- if no small window, get the selected object and process them
get the object ids from selected objects, then process the ids.
- otherwise, select all objects in the thumbnails and prompt user
get the object ids from users, then process the ids.
- Process the id
- find the object type.
- get the metadta service url from id using service call [domain]/[approot]/secure/metadata/id
- fetch and convert the metadata from the metadata service call
- take into consideration of different metadata field for the portals
- may need to convert/format the data values.
- fetch the item notes using:
- get the resource link url from id: :[domain]/[approot]/secure/metadata/id?_method=FpHtml
- fetch the resource from resource url
- set the item title and item mine type.
doWeb is run when a user, wishing to save one or more items, activates the selected translator.
Sidestepping the retrieval of item metadata, we'll first focus on how doWeb can be used to save
retrieved item metadata (as well as attachments and notes) to your Zotero library.
