- fixes a bug that could result in the Scrape Progress chrome thingy sticking around forever
- makes chrome thingy disappear when URL changes or when tabs are switched
Item.addSeeAlso(itemID)
Item.removeSeeAlso(itemID)
Item.getSeeAlso() -- array of linked items
Relationships are mutual
Closes#82, Notes: see also table
- changes scrapers table to translators table; all import/export/web translators now belong in this table
- adds Scholar.Translate to handle translation issues. eventually, Scholar.Ingester.Document will become part of this interface
- adds Scholar_File_Interface (in fileInterface.js) to handle UI for export and eventually import. (David, when you have time, please connect Scholar_File_Interface.exportFile to a button.)
- adds an export translator for MODS. all of our metadata, but not our hierarchy (projects, etc.) translates directly and unambiguously into valid MODS. eventually, we can use RDF or another format to handle hierarchy.
- adds utilities.getVersion() and utilities.inArray() for simplified scraper coding
- fixes minor interface issues with the nifty chrome scraping status window
New methods:
Item.addTag(tag)
Item.getTags() -- array of tagIDs
Item.removeTag(tagID)
Tags.getName(tagID)
Tags.getID(tag)
Tags.add(text) -- returns tagID of new tag
Tags.purge() -- purge obsolete tags
The last two are for use by Item.addTag() and Item.removeTag(), respectively, and probably don't need to be used elsewhere.
Item.save() changed to not call notify() if a transaction is in progress, which is totally going to trip someone up at some point, and probably me, but it's better than a new parameter
Item.toArray() implemented -- builds up a multidimensional array of item data, converting all type ids to their textual equivalents -- currently has empty placeholder arrays for tags and seeAlso
Sample source output:
'itemID' => "2"
'itemType' => "book"
'title' => "Computer-Mediated Communication: Human-to-Human Communication Across the Internet"
'dateAdded' => "2006-03-12 05:25:50"
'dateModified' => "2006-03-12 05:25:50"
'publisher' => "Allyn & Bacon Publishers"
'year' => "2002"
'pages' => "347"
'ISBN' => "0-205-32145-3"
'creators' ...
'0' ...
'firstName' => "Susan B."
'lastName' => "Barnes"
'creatorType' => "author"
'notes' ...
'0' ...
'note' => "text"
'tags' ...
'seeAlso' ...
'1' ...
'note' => "text"
'tags' ...
'seeAlso' ...
'tags' ...
'seeAlso' ...
Sample note output:
'itemID' => "17"
'itemType' => "note"
'dateAdded' => "2006-06-27 04:21:16"
'dateModified' => "2006-06-27 04:21:16"
'note' => "text"
'sourceItemID' => "2"
'tags' ...
'seeAlso' ...
sourceItemID won't exist if it's an independent note.
We'll use the same format in reverse for fromArray, so Simon, let me know if you need more data (preserving type ids, etc) or want anything in a different form.
- Added 'note' item type
- Updated API to support independent note creation
Notes are, more or less, just regular items, with an item type of 1. They're created through Scholar.Notes.add(text, sourceItemID), which returns the itemID of the new note. sourceItemID is optional--if left out, an independent note will be created. (There's currently nothing stopping you from doing getNewItemByType(1) yourself, but the note would be contentless and broken, so you shouldn't do that.) Note data could've been stuffed into itemData, but I kept it separate in itemNotes to keep metadata searching faster and to keep things cleaner.
Methods calls that can be called on all items:
isNote() (same as testing for itemTypeID 1)
Method calls that can be called on source items only:
numNotes()
getNotes() (array of note itemIDs for a source)
Method calls that can be called on note items only:
updateNote(text)
setNoteSource(sourceItemID) (for changing source--use empty or false to make independent, which is currently what happens when you delete a note--will get option with #91)
getNote() (note content)
getNoteSource() (sourceItemID of a note)
Calling the above methods on the wrong item types will throw an error.
*** This will break note creation/display until David updates interface code. ***
- Move processDocuments, a function for loading a DOM representation of a document or set of documents, to Scholar.Utilities.HTTP
- Add Scholar.Ingester.ingestURL, a simplified function to scrape a URL (closes#33)
- This required moving the icon to the title field so that the indent would work out right. The type column (which for new installs will be hidden) displays the type in text.
- I expect several small bugs in regard to this.
closes#26, notes list in notes pane
closes#79, add icons for new object types
fixes#71, Metadata pane should be refreshed on a notify() event for the selected item
- Added detection for network failure -- debug message is output and noNetwork property is added to the xmlhttp object
- Removed onStatus callback from HTTP.doGet and HTTP.doPost -- that was copied over from the Piggy Bank API, but the onDone callback has to handle errors anyway, so it can just check the status code if it actually cares to differentiate non-200 status codes from any other error
- Added error handling for empty responseXML to Schema._updateScrapersRemoteCallback
- Renamed SCHOLAR_CONFIG['REPOSITORY_CHECK_RETRY'] to SCHOLAR_CONFIG['REPOSITORY_RETRY_INTERVAL']
Scholar.Prefs also registers itself as a preferences observer and can be used to trigger actions when certain prefs are changed by editing the switch statement in the observe() method
Updated preferences.js to use Scholar.Prefs
- Added methods getID(idOrName) and getName(idOrName) to Scholar.CreatorTypes and Scholar.ItemTypes to take either typeID or typeName
- Removed getTypeName() in each and changed references accordingly
- Streamlined both classes to be as similar as possible
- Make Amazon scraper work with multiple documents
- Fix bugs in processDocuments
- Make Scholar.Ingester.Utilities.getItemArray() willing to take an array of DOM nodes to search for links, and finally take advantage of the fact that objects have no length
- Multiple item detection code is now a part of the scraperJavaScript, rather than the scrapeDetectCode, and code to choose which items to add is part of Scholar.Ingester.Utilities, accessible from inside scrapers. The alternative approach would result in one request (or, in the case of JSTOR, three requests) per new item, while in some cases (e.g. Voyager) only one request is necessary to get all of the items.
Moved the capture icon into the URL bar (invisible until you visit a scrapable page. Currently just displays a Book, but will change to the correct item types in the future?)
- When possible, corporate creators/contributors are categorized with their own RDF types (prefixDummy + "corporateCreator/corporateContributor)
- Remove extraneous debug code in extensions
- Don't try to display an SQLite error when it's "not an error" (i.e. when the error is in something else)
- Switch to nsIFile instead of nsILocalFile to retrieve the profile directory
Fix in Collection.erase() -- when the DB methods started returning values in their native type, the collection id became an int rather than a string and "new Array(this._id)" became a length declaration rather than an elements declaration
- Ingester lets callback function save items, rather than saving them itself.
- Better handling of multiple items in API, although no scrapers currently implement this.
- Fix item modify notify() on 1st row.
- Ensure that new items are visible when added.
- New functionality for creating new items (prevents a lot of problems).
- Number-based fields display properly.
- Fixed bug when creating and saving the first notes on an item.
- New notes won't save empty.
[fix] You shouldn't lose your changes if you select another item in the middle of editing a field.
[fix] The dropdown menu to select notes doesn't steal the focus
[interface] Multi-notes functionality (waiting on data layer)
[docs] Major internal documentation written for itemTreeView.js and collectionTreeView.js (this actually does work ;-))
Added a separate retry interval so that the extension retries sooner after failures (browser offline, request failure, etc.)
Revision 200 -- w00t i am victorious
- Removed localLastUpdated field from scrapers table and renamed centralLastUpdated to lastUpdated; updated scraper queries accordingly
- Added query in scrapers.sql to update version table 'repository' row to prevent immediate downloads of newly installed scrapers
- Get version property from extension manager in Scholar.init() and assign to Scholar.version
[Drag and Drop] in Items Tree: You can drag items from one window into another, directly into the Items list.
[Editing] Close the edit box and save when you click on its label
The collections list does not resize randomly now.
The pane on the right stays open all the time - even when 0/multiple items are selected. This is to avoid frequent resizing of the items pane.
Temporarily, if the first "word" of a field's value is more than 29 characters long, it will set it to crop. This is for the long URLs, etc.
Scholar.HTTP.doGet(url, onStatus, onDone) and Scholar.HTTP.doPost(url, body, onStatus, onDone) -- onStatus and onDone are callbacks to call on non-200 responses and the response body, respectively
Assigned guids to scrapers, replaced INSERT queries with REPLACE queries, and removed table DELETE query at top -- this will allow scrapers to be updated without deleting any others that may exist (e.g. that someone is developing, third-party, etc.)
[style] Better add/remove Creator buttons.
[fix] The sorting should not randomly switch the order of two items with the same sort value (eg, Barnes vs. Barnes).
[fix] The browser should not open with two sorted columns.
scholar.properties addition is just to keep metadata panel from breaking and could probably be removed once interface is hard-coded to not display the notes field there
- Send a 'delete' rather than a 'remove' to itemViews when items are actually deleted (removals from collections still get 'remove' unless it's part of a collection erase)
1) Items into collections.
2) Collections into collections.
Dan S, please check this out, I am getting some exceptions from the data access portion.
[interface] Temporarily, "metadata" pane on the right is not resizable.
Added creatorTypeID to the PK in itemCreators, because a creator could conceivably have two roles on an item
Throw an error if attempt to save() an item with two identical creator/creatorTypeID combinations, since, assuming this shouldn't be allowed (i.e. we don't have a four-column PK), there's really no way to handle this elegantly on my end -- interface code can use new method Item.creatorExists(firstName, lastName, creatorTypeID, skipIndex), with skipIndex set to the current index, to make sure this isn't done
Integrated the scrapers with the schema update mechanism. Changed a bunch of schema methods to handle both schema.sql and scrapers.sql (or others, if need be) and altered the version table to track mu
ltiple versions for different files. This theoretically should detect that the version table has changed and force a reinitialization of the DB--let me know if there are problems.
- Broke schema functions into separate object and got rid of DB_VERSION config constant in favor of a toVersion variable in the _migrateSchema command (which isn't technically necessary either, since the version number at the top of schema.sql is now always compared to the DB version at startup) but will help reduce the chance that someone will update the schema file without adding migration steps)
- Removed Amazon scraper from schema.sql, as it will be loaded with the rest of the scrapers
- Lots of work to be done. For example, the present way of showing a textbox is sort of a hack - taking a label, assigning certain properties to a textbox, then removing the label and placing the textbox in its place. I will be looking into our options.
- Also, I need to figure out adding/editing/deleting creators.
- When the textbox loses focus, it updates and saves the item (like iCal).
Date: removed Scholare.Date functions, as they are overkill. We can use the built-in Date.toLocaleString()
- Implemented loadDocument API, for loading and parsing the DOMs of HTML documents in the background
- Added scraper code to SVN repository (now includes 12 scrapers, see Writeboard for details)
To update to the latest versions of all scrapers, ensure you have an up-to-date version of sqlite3, then run:
sqlite3 ~/Library/Application\ Support/Firefox/Profiles/profileName/scholar.sqlite < scrapers.sql
The real search function will be considerably more advanced/flexible, but this should work as a placeholder for the moment. Probably quick enough for FAYT, at least with a ~0.5 second delay to avoid unnecessary calls while people are typing (which is probably a good idea anyway). This search doesn't use indexes at all, so if more speed is needed, one option would be to maintain a manual FULLTEXT-type index (using triggers, ideally) that could be quickly searched, but we'd lose intra-word filtering, which people would probably expect...
parentCollectionID is optional and defaults to moving item to root
Returns true on success, false on attempt to move collection into its existing parent, itself or a descendent collection; throws exception on invalid parentCollectionID
Sends a columnTree notify() with previous parent ID, id of collection itself, and new parent ID (unless the previous or new are the root, in which case it's omitted) -- that may or may not make sense for the interface code and can be changed if needed
New items are automatically selected.
When adding a new item, or editing an item without a creator, display an empty creator box.
Edit button changed from toggling to Save/Cancel buttons.
Simple "Do you want to save changes?" dialog if you select a different item while in edit mode.
- Collection.add( name [, parentCollectionID] ) -- saves new collection in DB and returns new Collection object; defaults to root if parent not provided
Currently some exceptions in folderTreeView.js when notified on collection add
- Added back Item.isCollection() and Collection.isCollection(), as they seem to still be used
- Collection._load() now takes optional ids for loading new collections
Close buttons on the Metadata and Notes.
The Collections list no longer throws an exception when the header is clicked.
More minor interface improvements.
This behavior of JS has some implications for how interface code handles things like deletes. The following won't do what one might expect/desire (and my apologies if this is obvious or redundant, but I figure it's worth pointing out):
var item = Scholar.Items.get(1);
Scholar.debug(item);
Scholar.DB.query("DELETE FROM items WHERE itemID=1");
Scholar.Items.reloadAll();
Scholar.debug(item);
The last line will still display the old object, even though _items[1] has been deleted inside Scholar.Items. The following does work, however:
var item = Scholar.Items.get(1);
Scholar.debug(item);
Scholar.DB.query("DELETE FROM items WHERE itemID=1");
Scholar.Items.reloadAll();
var item = Scholar.Items.get(1);
Scholar.debug(item);
Now item is properly undefined. Moral of the story: object references need to be deleted manually after receiving delete notifications, for if external code still has references to deleted data objects, the data layer can't do much about it.
Revised the way the dateAdded and dateModified columns are displayed.
Views are now unregistered on window close.
A few functions in overlay.js were renamed.
Began better commenting of the interface code.
Although I do not yet have interface code for it, collections do not have any sort of setName(), save() functions.
Collections list now implements notify()
Made some fixes on itemTreeView to allow for notify() on multiple deletes
(shifts the row identifier up 1 for each previous delete, etc.)
One more thing -- this might not happen because the tree calls each Item.erase() or Collection.removeItem() individually.
Bug fix on notifier.js so that register*Tree() actually returns the hash. :-)
Unfortunately, unregister*Tree() does not seem to actually work, there is still an object at _observers['itemTree'][hash]
(temporary): When you select an item Scholar no longer loads a page into the browser.
The javascript bugs on those HTML pages were frustrating the debugger.
- Added Notifier triggers to Item.erase() (which only runs if not in a nested transaction) and Collections.erase()
- notify() in ItemTreeView updated with example of taking multiple ids, though it doesn't actually work (and notify() implementations may decide just to refresh the whole tree when ids.length>1 rather than dealing with changes individually)
- When deleting collections, use DB tables that actually exist
Scholar.Notifier framework to handle update notifications between data layer and interface
- Notifier.registerColumnTree(ref) and Notifier.registerItemTree(ref) pass back a unique hash that can be used to unregister the tree later with unregister*(hash) (and must be, lest we leak treeViews and probably entire browser windows if the browser window is closed without unregistering the treeView)
- Data layer calls Scholar.Notify.trigger(event, type, id) after various events (only two calls in the data layer at the moment--more coming later)
- Notify.trigger() calls notify(event, type, id) on all registered trees of the appropriate type -- the data layer usually knows what collection the action pertains to, but we decided that it's cleaner to just let the tree decide what it wants to do rather than add all that logic into the data layer)
(Note: Item collection adds appear to be buggy on the interface side, but removes seem to be working)
