Slate v0.11.9!

Welcome to Slate

Server Setup

Setting up Slate is fairly easy. Basically you need to:

  1. Install Tomcat 5.x or 6.x
  2. Replace the webapps/ROOT/ folder with the contents of the war package (the war package must be built first; see "Building Slate below").
  3. Run the SLATE_SCHEMA.sql file once as root (sudo) to create the DB and DB user
  4. Start up Tomcat and hit it in web browser to configure (e.g. http://localhost:8080/)

Building Slate

You must have ant in your path to build the project via the command line. You can then build it as a directory, or as a .war file.

  1. Change the properties that point to jUnit and GWT SDKs inside the build.xml file.
  2. Build as a directory.
    1. Run ant build to build the project
    2. After the project has built, the application files can be found in war/.
  3. Run ant war to build and package the project as a war file.

If you are using Eclipse, you can import the project folder as an existing project (there is a .project file), or using the build.xml (not recommended).

GWT 2.4 and Eclipse

GWT 2.4 uses annotation processors that are required to run the app. Make sure you follow these instructions to enable it or the project will not run (though it will start up): http://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation

The SLATE_SCHEMA.sql file

This file creates a slate2 database, along with a slate user with full privileges on that database.

First time initialization

When you access slate in a web browser for the first time, it will show you a screen for creating the master (root) user. Don't forget the password you enter here or you will not be able to login to create other users.

Changing the database name

If you want to change the DB name that is used, you need to modify two places. 1. Change the SLATE_SCHEMA.sql file (rename slate2 to whatever you want) 2. If you are editing an active installation, open war/WEB-INF/classes/hibernate.cfg.xml and rename the DB connection string, replacing slate2 with whatever you used in 1; if you are editing source (and will build after), modify src/main/wibernate.cfg.xml and then build with ant.

Customizing

Slate has a number of easily extensible points to allow you to customize its behavior.

  1. Importer/Exporter API
  2. Annotation Screen Controls Panel

Importer/Exporter API

Slate has the ability to use custom importers / exporters if they properly follow a defined standard. On start up the system scans the war/WEB-INF/lib/plugins/ folder (this folder is copied from lib/plugins at build time). Under src/ there are two plugin related subfolders, plugins/ to plugins-api, containing built-in IO plugins (and concrete framework implementations) and the public plugin framework API, respectively. When an administrator tries to import/export data, the plugin framework is used to generate the UI to let the user configure how data is treated; then the plugin is used to transform the data. Both importer and exporter classes are POJOs with annotations marking methods for the framework to call. It functions similarly to jUnit, so if you are familiar with this then plugin creation should be a breeze. In order to create an importer/exporter you need to understand the Slate data model. See the WIKI for more info.

Annotation Screen Controls Panel

The annotation screen has a panel on the side where controls exist that the user can interact with ("controls panel"). These can be customized (new ones added) if you need to customize the system for a specific project. Essentially, any GWT widget can be added to the controls panel. If you want this control to interact with a server-side data service, simply make your widget do this. When segments are selected/created/deleted/changed events are dispatched, which can also be hooked into if necessary. See the WIKI for more info.

Revision history

The following is a list of bugs fixed, enhancements added for each release.

  • Added SciXML (AZ) importer plugin

v0.11.9

  • ENH #122: Adjusting lines of segment using keys

v0.11.8

  • ENH #116: Fix CSS styles in Firefox and IE

v0.11.7b

  • BUG #115: MS Windows does not always display annotations properly within the Flash annotation screen
  • Further extended ENH #114 by pulling flash related SLAC code into its own package

v0.11.7

  • BUG #113: Attributes with spaces in their names break annotation screen interface
  • ENH #114: SlacWidget must be an interface so the Flash implementation can be easily replaced

v0.11.6

  • BUG #110: Deleting document set now will succeed even with documents inside
  • ENH #109: Added document name to Slat exports
  • Reformatting of palette widget
  • Updating flash copy script to allow for copying release and debug builds
  • UI updates for buttons.

  • Fixing bug where clicking "export from project" on project details screen takes the user to the export screen with the project pre-selected, but the corpus versions list empty
  • Fixing issue where segment deletion while attached to a link causes annotation screen to break. This makes all attached links auto delete when the segment is deleted.

v0.11.5

  • Clicking "Add value" now focuses on the newly added field
  • Adding hibernate annotations so deletes will cascade properly (including deletion of corpus versions)
  • Added more styling to the "Working…" status display at top of screen

  • UI tweaks

v0.11.4

  • UI tweaks
  • Fixing NPE for segments without string content
  • Moved editors to their own package (ui.editors) and modified css a bit
