Total Library Solution (TLS) is a suite of Free and Open Source Software in a live DVD having Koha, DSpace, WordPress, etc.

This document discusses using Drupal 7 as a content management system for publishing special collections as linked open data. It provides an overview of how Drupal allows customizing content types and fields for mapping to RDF properties. While Drupal 7 provides basic RDFa support out of the box, there are some limitations around nested RDF structures and multiple entities per page that may require custom code. The document outlines some additional linked data modules for Drupal 7 and highlights improved RDF support anticipated in Drupal 8.

Publishing Linked Open Data in a user-appealing way is still a challenge: Generic solutions to convert arbitrary RDF structures to HTML out-of-the-box are available, but leave users perplexed. Custom-built web applications to enrich web pages with semantic tags "under the hood" require high efforts in programming. Given this dilemma, content management systems (CMS) could be a natural enhancement point for data on the web. In the case of Drupal, one of the most popular CMS nowadays, Semantic Web enrichment is provided as part of the CMS core. In a simple declarative approach, classes and properties from arbitrary vocabularies can be added to Drupal content types and fields, and are turned into Linked Data on the web pages automagically. The embedded RDFa marked-up data can be easily extracted by other applications. This makes the pages part of the emerging Web of Data, and in the same course helps discoverability with the major search engines. In the workshop, you will learn how to make use of the built-in Drupal 7 features to produce RDFa enriched pages. You will build new content types, add custom fields and enhance them with RDF markup from mixed vocabularies. The gory details of providing LOD-compatible "cool" URIs will not be skipped, and current limitations of RDF support in Drupal will be explained. Exposing the data in a REST-ful application programming interface or as a SPARQL endpoint are additional options provided by Drupal modules. The workshop will also introduce modules such as Web Taxonomy, which allows linking to thesauri or authority files on the web via simple JSON-based autocomplete lookup. Finally, we will touch the upcoming Drupal 8 version. (Workshop announcement)

Databases require capacity planning (and to those coming from traditional RDBMS solutions, this can be thought of as a sizing guide). Capacity planning prevents resource exhaustion. Capacity planning can be hard. This talk has a heavier leaning on MySQL, but the concepts and addendum will help with any other data store.

This document provides an overview and summary of key concepts related to advanced databases. It discusses relational databases including MySQL, SQL, transactions, and ODBC. It also covers database topics like triggers, indexes, and NoSQL databases. Alternative database systems like graph databases, triplestores, and linked data are introduced. Web services, XML, and data journalism are also briefly summarized. The document provides definitions and examples of these technical database terms and concepts.

A decade ago, the database was assumed to be a solved problem. Relational databases (PostgreSQL, MySQL, SQLite to name a few) were dominating the database market and hierarchical databases (LDAP, DNS) where regarded as niche solutions. The NoSQL revolution surely changed the concept of what a database can be. At the same time, the popularity of mobile devices exploded. This talk will dive into how data structures are persisted and queried on mobile devices today, and try to revive the old question: is the database really a solved problem?

This document provides an overview of MariaDB, including: - MariaDB is an open-source database that is a fork of MySQL with additional features and enhancements. - It was first released in 2009 and is overseen by the MariaDB Foundation. SkySQL, formed by former MySQL executives, merged with MariaDB founder Michael "Monty" Widenius' company in 2013. - MariaDB offers various storage engines, new features like dynamic columns and NoSQL access, and generally better performance than MySQL through optimizations and user statistics. It is widely adopted with major investors and supporters.

SortaSQL is a proposal to add seamless horizontal scalability to SQL databases by using the filesystem to store and retrieve data. The SQL database would store metadata and handle queries, while an embedded key-value store manages record storage on files in the local or distributed filesystem. This allows queries to scale across many servers by letting the filesystem handle replication, performance and locking of distributed data files. The architecture involves an application communicating with PostgreSQL over SQL, which uses a SortaSQL plugin to retrieve rows from Kyoto Cabinet key-value files on the POSIX filesystem. Case studies at CloudFlare show how a 400GB per day dataset can be efficiently stored and queried at scale using this approach.

A last minute talk for the people at DevOps Amsterdam, happening around the same time as O'Reilly Velocity Amsterdam 2016. Here are lessons one can learn from distributed/remote/virtual communities and companies from someone that has spent a long time being remote and distributed.

This document discusses Open Atrium, an open source intranet platform built with Drupal. It describes Open Atrium's core features for blogs, wikis, calendars, to-do lists, and more. It also provides examples of how Open Atrium can be customized and extended through the use of Drupal modules like Features, Spaces, and Organic Groups to create public websites, private groups, social networks, and other configurations. The document includes code snippets demonstrating how to customize user profiles, override core configurations, alter contexts at runtime, and remove blocks using various Drupal hooks and modules.
