Current Extensions

PROs+ Some stable Extensions+ TYPO3 Look & Feel+ Community support

Current Extensions

CONs- TYPO3 Look & Feel- Ugly Codebase- Poor Documentation- No Backend Module- Not suitable for many pictures- Out-of-date (last update 2004...)

YOU DON‘T WANT TO USE THEM!

YAG Goals

Clean Codebase (Extbase approach) Extendable (Theming & API) Scalable (T3 caching) Easy to manage (BE Module) Strict seperation of gallery

management and frontend representation

All features known from„Big Galleries“ EXIF, Lightbox, Multifile-Upload,

Skinning, ...

Where we are today

Some installations with up to 15.000 photos (and growing) on high-traffic sites Scalable *check*

Skinning (different theme packages available in TER) Extendable *check* Skinning *check*

Further Goals

Well-integrated in TYPO3 Flexible Resolution handling &

caching Interfaces for Desktop Applications

(e.g. Lightroom) Flexible Filtering of images (tags,

categories, EXIF data, ...)

Conceptsbehind YAG

Typoscript

Template

So easy to build your own theme!Include Javascript

Template

Inline Javascript with Fluid can be pure pain.

Our approach: JS Template ViewHelper

<yag:Javascript.template templatePath="EXT:../JSTemplates/CustomScript.js"

addToHead=„1"arguments="{key1:‚value', key2:‚value2'}

/>

Javscript Template

function demo() {

if(###key1### == value) {alert(###LLL:tx_yag_controller_gallery.sortingSaved###);

}}

So easy to build your own theme!Include Javascript

The missing parts

Categories

Our goal: Having generic categories for multiple

extensions Having (ExtJs) Tree-Widget for editing

categories

Frontend Editing

Let FE Users Create / Edit / Delete▪ Galleries▪ Albums

Upload / Edit / Delete▪ Images

in Frontend

Supporting PIDs

Issue: All records are stored to PID 0 Impossible to assign permission to records

on page level. Impossible to split data between different

authors

Todo Add Sysfolder / Page selector to BE module Add Sysfolder / Page selector to CE Keep it simple and usable!

Supporting Localization

Issue: Add multilanguage support to item labels and descriptions
