Currently a large number of Web sites are driven by Content Management Systems (CMS) which manage textual and multimedia content but also - inherently - carry valuable information about a site's structure and content model. Exposing this structured information to the Web of Data has so far required considerable expertise in RDF and OWL modelling and additional programming effort. In this paper we tackle one of the most popular CMS: Drupal. We enable site administrators to export their site content model and data to the Web of Data without requiring extensive knowledge on Semantic Web technologies. Our modules create RDFa annotations and - optionally - a SPARQL endpoint for any Drupal site out of the box. Likewise, we add the means to map the site data to existing ontologies on the Web with a search interface to find commonly used ontology terms. We also allow a Drupal site administrator to include existing RDF data from remote SPARQL endpoints on the Web in the site. When brought together, these features allow networked RDF Drupal sites that reuse and enrich Linked Data. We finally discuss the adoption of our modules and report on a use case in the biomedical field and the current status of its deployment.

Drupal with CONTENTdm Digital Collections, Drupal Camp Vancouver 2012Marcus Emmanuel Barnes
CONTENTdm is a digital collections management application that provides several important administration features of value when undertaking a digitization project. Many institutions already use Drupal to power their web presence. CONTENTdm's native interface makes creating a single integrated website difficult. The CONTENTdm Integration Modules project was created by Mark Jordan of Simon Fraser University Library to solve this issue by providing a series of Drupal modules that help create a single integrated website - allowing the searching of digital collections hosted in a CONTENTdm server from within a Drupal website.
By the end of this talk, you will have a better understanding of:
*Why you would want to use CONTENTdm rather than simply Drupal for digital collections management;
*How the CONTENTdm Integration Modules work under the hood;
*How to install and setup these modules with Drupal to help present an integrated website.
This talk will be of particular interest to those who develop Drupal websites for use in libraries, archives, or museums, but also to Drupal developers and administrators in general.
Linked Data Publishing with Drupal (SWIB13 workshop)Joachim Neubert
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)

If you have a new web project or and existing Drupal site, the combination of Drupal and Apache Solr is both powerful and easy to set up thanks to the existing integration code. The module allows for substantial customization with the administrative UI. Drupal facilitates further customizations of the UI, indexing, and bosting because of the open architecture that provides multiple opportunities for custom code to alter the behavior. A couple code snippets will be followed by a review of other contributed Drupal modules that further enhance the search capability.
Finally, this session will showcase some example of Drupal sites using Solr including Acquia's own sites and Drupal sites including many well-known Enterprise and government sites.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

3. Some Motivations...
Digital Enterprise Research Institute www.deri.ie
Status of the current web
Data contained in millions of documents
Disparate platforms and systems
Wide range of topics (personal blogs, news, etc.)
Various types of resources (text, pictures, video, etc.)
Note: Lots of Structured data in Content Management Systems
Problem
Not possible to reuse this data outside the CMS (except RSS)
Not available as unified machine readable format
3
4. So, here’s our idea of CMS:
Digital Enterprise Research Institute www.deri.ie
PROJECT BLOGS
DBLP
SPARQL
endpoint
SPARQL REMOTE DRUPAL SITE
endpoint
SELECT ?name ?title Tim
WHERE { .........
?person foaf:made ?pub.
?person rdfs:label ?name.
?pub dc:title ?title. SPARQL
FILTER regex(?title, "knowledge", "i") endpoint
}
Figure 3.5: Extended example in a typical Linked Data eco-system.

5. Approach
Digital Enterprise Research Institute www.deri.ie
Our Goal
Integrate "any" CMS site to the Web of Data
A challenging task
Little incentive for users to annotate their data manually
Site owners do not have the resources to convert their data to RDF
Per-siteschema: each site is different and its structure cannot be
predefined
Solutions
Expose the CMS site structure in a unified format AUTOMATICALLY!
Use Semantic Web standards (RDFa, SPARQL)

6. Approach
Digital Enterprise Research Institute www.deri.ie

Why? One of the most popular CMS out there
Modules to take the burden off the site users
What our modules allow:
