|''Version:''|1.0.1|
|''~CoreVersion:''|2.1.x|
|''Browser:''|Firefox 1.5/2.0; Internet Explorer 6.0/7.0; Safari|
|''Require:''|LightBoxCSS (see below), support HTML in MarkupPreHead (see below), access to icon images in subdir ''im'' (showAlert() only)|
!Description
This plugin implements a lightbox widget for ~TiddlyWiki. Via Javascript, you can display any HTML div in the lightbox, or use "canned" divs for displaying HTML message in a box or an alert with icon. The lightbox is closed by either clicking the X-icon or anywhere outside the lightbox. Only one lightbox can be active at a time. See the usage section below.
!!Usage
This plugin is a __library__, not a macro. Thus, it must be tagged {{{systemConfig}}}, but it does not support macro invocation. It is callable only from Javascript so the [[InlineJavascriptPlugin|http://www.tiddlytools.com/#InlineJavascriptPlugin]] is a virtual necessity!
|!Usage|!Sample Javascript|
|Display HTML message|{{{DC3.LightBox.showContent("Some <i>message</i>");}}}|
|Display alert|{{{DC3.LightBox.showAlert("ok", "All is well");}}}|
|Display any DIV in a lightbox|{{{DC3.LightBox.showBox("myLightBox");}}}|
|Close current lightbox|{{{DC3.LightBox.hideBox()}}}|
*The frame for the showContent() and showAlert() methods should expand to enclose text, but this happens only on IE and not FireFox. To be safe, just keep your messages short and use showBox() and your own HTML div for "big" messages etc.
*The first parameter to showAlert() is the icon name. This is simply translated to {{{im/icon.png}}}. The standard icon image files (below) are used with icon strings of "error, "info", "ok", "question", and "warning". 
*The generalized showBox() method can be used to display images, media players, whatever you want! Just make up the HTML div, give it an id, then pass that ID to showBox().
!!Advanced Usage - onClose
All three of the above methods support an optional parameter onClose, supplied as the last parameter in a call. It must evaluate to a function which is called (with no parameters) when the lightbox is about to close. If the onClose() function returns false, the lightbox will not be closed. For example 
{{{
DC3.LightBox.showAlert("warning", "Something <em>bad</em> is about to happen", soundBuzzer);
}}}
!Installation
#Paste this entire tiddler into a tiddler called DC3.LightBox and tag it {{{systemConfig}}}.
#Paste the Required CSS (below) into a tiddler called LightBoxCSS and tag it {{{systemContent}}}.
#Paste the content for MarkupPreHead (below) into MarkupPreHead.
#Put the image files (below) into a subfolder ''im'' relative to the location of the TiddlyWiki. 
!!!Required CSS
Paste into a tiddler called LightBoxCSS.

!!!Images (close box and alert icons)
These must be in a subfolder ''im'' below the ~TiddlyWiki. You can get the images by right clicking on the links and //save target/link//, or right clicking on the images and //save image//. @@Note: The images below will display ugly in IE6, but they will display nice (with transparency) in the lightbox alerts, owing to the use of the DXFilters for transparency in the code.@@

!!Credits
This TiddlyWiki library and CSS is an amalgamation of the techniques and code described in the following: 
* [[Original LightBox|http://www.huddletogether.com/projects/lightbox/]] by Lokesh Dhakar
* [[Lightweight LightBox|http://www.pjhyett.com/posts/190-the-lightbox-effect-without-lightbox]] that can show any DIV by PJ Hyett
* [[Better Modal Windows with LightBox|http://blog.feedmarker.com/2006/02/12/how-to-make-better-modal-windows-with-lightbox/]] by Bruno
Bruno's CSS for the overlay is much better than the first two, it is independent of any PNG image(s) and does not have CSS quirk-hacks for IE, nor does it use IE's DXFilters for PNG transparency. Of course for IE6, the DXFilters are used in the Javascript!

<<<
''2006.12.02 [1.0.1]'' Initial creation
''2006.12.03 [1.0.1]'' hideBox() no longer takes //id// just closes currently open box. Needed for overlay click/close.
''2006.12.03 [1.0.1]'' Add support for special Alert type LightBox with switchable icon. Hack IE for alpha transparency. See inline comments. Add showContent(html), showAlert(icon, message)
''2006.12.04 [1.0.1]'' Ignore show calls if box is already displayed. Optional callback for hideBox(), can prevent hiding. Allows modal box to be set up by caller.

Geo-Stream is a term we used to describe the general real-time streaming data that are geo-referenced and produced by sensors and sensor networks.
!!!Examples of Geo-Stream
* Point Geo-Stream: Continuous GPS location that forms a breadcrump trail
* Line Geo-Stream: A dynamic route to the destination avoiding traffic
* Region Geo-Stream: An evolving forest fire zone

Sensor networks are expected to form a digital nervous system embedded in physical spaces and extend human beings’ “tactile” sensations to every corner of the world. As a result, the volume of real-time streaming data (many are ''geo-referenced'') produced by sensors and sensor networks is staggeringly large and growing rapidly.

We envision a Sensor Web 2.0 era where average users and organizations can feed their sensor data, such as data from the hydrological sensor network a city manages, GPS trajectories encoding traffic information, and temperature in one’s backyard, through standards as ''geo-stream''s. However, neither data stream management systems nor spatio-temporal databases/moving object databases today provide the necessary support to answer many important spatially explicit queries on geo-streams.
!!!We list three motivating queries that are challenging for current systems:
* Point Geo-stream:
{{{
Continuously report the nearby scenic landmark while driving in a national park. 
}}}
* Line Geo-stream:
{{{
Continuously find a route from my current location to destination avoiding hurricane.
}}}
* Region Geo-stream:
{{{
Continuously report the spatial extent of the evolving flooding zone.
}}}
!!!The goal of the research is to build a  real-time geo-stream processing and monitoring system that: 
# unifies geo-streams and large volumes of static infrastructure datasets that have been accumulated over the years
# allows spatially explicit monitoring queries
# spits out results in real time even in disastrous situations when data volumes are often high. 
!!! As part of this endeavor, this site outlines our research proposal and introduces some of our preliminary work towards building such a system.
A brief demo of our preliminary work can be found [[here |Preliminary Work]]. More details can be found in the demo paper [[here |Publications]]. Source code for an early test version can be downloaded [[here |Downloads]]. For more questions, please feel free to [[contact us|Contact Us]].

<<<
2008.06.11 [1.9.3] added $(...) function as 'shorthand' convenience syntax for document.getElementById()
2008.03.03 [1.9.2] corrected declaration of wikifyPlainText() for 'TW 2.1.x compatibility fallback' (fixes Safari "parse error")
2008.02.23 [1.9.1] in onclick function, use string instead of array for 'bufferedHTML' attribute on link element (fixes IE errors)
2008.02.21 [1.9.0] 'onclick' scripts now allow returned text (or document.write() calls) to be wikified into a span that immediately follows the onclick link.  Also, added default 'return false' handling if no return value provided (prevents HREF from being triggered -- return TRUE to allow HREF to be processed).  Thanks to Xavier Verges for suggestion and preliminary code.

Our ''gStream'' is a general Geo-Stream query engine built upon an open source database platform called [[SECONDO|Useful Links]].
!!!Prototype System Architecture
Our gStream query engine prototype mainly consists of three components: 
* geo-stream algebra
* standalone parser
* web-based user interface.

!!!! Towards building a real time Geo-Stream Query Engine, we have done some preliminary work in adding Geo-Stream support into an open source database platfrom called SECONDO. 
!!!Here are a few demo videos for this early-stage work.

!!!Link to the Web GUI
The following link redirects you to our web GUI. This is still under development. So expect bugs. There are currently performance issues in processing large geospatial streaming data. And you are welcome to report bugs from [[here|Contact Us]].
[[http://powerranger.cse.unt.edu/stream_visualization/index_n.php|http://powerranger.cse.unt.edu/stream_visualization/index_n.php]]

!!!We propose to expand our preliminary prototype to support:
* ''Integration ''of Geo-Stream data types, operators and languages that are {{{generic}}} to avoid cluttering, {{{succinct}}}, representative with intuitive semantics, {{{consistent}}} with existing ones, and {{{closed}}} so that operators only result in known data types.
* ''abstraction ''of common aggregations needed for different spatial extents and investigate language extensions and efficient algorithms to process them.
* ''Optimization'' of query execution, including operator scheduling and incremental filtering.
* ''Implementation'' of a generic Geo-Stream query and monitoring system against a large benchmark dataset and queries.

|Description|Show tiddlers one at a time with automatic permalink, or always open tiddlers at top/bottom of page.|
This plugin allows you to configure TiddlyWiki to navigate more like a traditional multipage web site with only one tiddler displayed at a time.
!!!!!Documentation
>see [[SinglePageModePluginInfo]]
!!!!!Configuration
<<<
<<option chkSinglePageMode>> Display one tiddler at a time
><<option chkSinglePagePermalink>> Automatically permalink current tiddler
><<option chkSinglePageKeepFoldedTiddlers>> Don't close tiddlers that are folded
><<option chkSinglePageKeepEditedTiddlers>> Don't close tiddlers that are being edited
<<option chkTopOfPageMode>> Open tiddlers at the top of the page
<<option chkBottomOfPageMode>> Open tiddlers at the bottom of the page
<<option chkSinglePageAutoScroll>> Automatically scroll tiddler into view (if needed)

Notes:
* The "display one tiddler at a time" option can also be //temporarily// set/reset by including a 'paramifier' in the document URL: {{{#SPM:true}}} or {{{#SPM:false}}}.
* If more than one display mode is selected, 'one at a time' display takes precedence over both 'top' and 'bottom' settings, and if 'one at a time' setting is not used, 'top of page' takes precedence over 'bottom of page'.
* When using Apple's Safari browser, automatically setting the permalink causes an error and is disabled.

UploadPlugin uses the following sequence for finding parameters :
#''macro'' parameters
#''Options'' saved in cookies
#''Plugin'' default values
!Options used by UploadPlugin
| Option | Value | Default |
|Upload Username: |<<option txtUploadUserName>>| |
|Upload Password: |<<option pasUploadPassword>>| |
|Url of the UploadService script: |<<option txtUploadStoreUrl urlInput>>| store.php |
|Relative Directory where to store the file: |<<option txtUploadDir urlInput>>| . (the script directory) |
|Filename of the uploaded file: |<<option txtUploadFilename urlInput>>| index.html |
|Directory to backup file on webserver^^(1)^^: |<<option txtUploadBackupDir urlInput>>| //null// (none/no backup) |
|Log in UploadLog |<<option chkUploadLog>> Trace Upload| true |
|Maximum of lines in UploadLog |<<option txtUploadLogMaxLine>>| 10 |

^^(1)^^No backup if Backup Directory is empty, the previous file will be overwritten. Use a '.' to backup in the script directory.

<<upload>> with these options.

!Upload Macro parameters
{{{
<<upload [storeUrl [toFilename [backupDir [uploadDir [username]]]]]>>
 Optional positional parameters can be passed to overwrite UploadOptions. 
}}}

!UploadToFile Macro Macro parameters
{{{
<<uploadTofile [filename [tiddlerTitle]]>>
 tiddlerTitle, filename: if omitted the title of the current tiddler
}}}
