Data is our Product: Thoughts on LOD SustainabilityRobert Sanderson
The document discusses sustainability of cultural heritage linked open data products. It defines sustainability as when running costs are less than value plus shutdown costs. Running costs include technology, content, and staffing. Value includes income, benefits to mission, and intangible benefits. Building sustainability requires maximizing usage, usability, trust, and loyalty among users. Usability, trust, and loyalty develop through community engagement and ensuring the data meets user needs. Sustainability ultimately depends on having championing people to build, support, and use the product.
L'impression 3D, comment atteindre les cadences industrielles ? Denis Roditi
L'impression 3D est-elle vraiment la révolution qu'on nous promet ? Va-t-elle bouleverser l'usine de demain ? Cette thèse professionnelle dresse un état des lieux de la fabrication additive et de ses axes d'amélioration. La révolution industrielle n'est pas encore là, mais elle se prépare !
Salvador Dali was a surrealist artist known for his strange and dreamlike paintings that combined abstract and unexpected images. He claimed his ideas came from his vivid dreams as a child and that he received messages from aliens through his mustache. His most famous work, "The Persistence of Memory", depicts melting clocks in a surreal landscape and exemplifies his dreamlike style of combining unexpected objects and images.
The document lists famous artists such as Botticelli, Raphael, Judith Leyster, Da Vinci, Durer, Rembrandt, Van Gogh, Warhol, Picasso, Close and Kahlo. It suggests that these artists created self-portraits that students can learn from as part of a lesson on 2D art self-portraits using pencil drawings.
Frida Kahlo was a Mexican painter born in 1907 who began painting after suffering severe injuries in a bus accident. She married fellow artist Diego Rivera in 1929 and exhibited her paintings in Paris and Mexico. Kahlo is considered one of Mexico's greatest artists and painted in a style influenced by indigenous Mexican culture and post-operation recovery. She died in 1954 and her artwork focusing on themes of identity, post-colonialism, and feminism has grown significantly in fame since her death.
Phidias was a famous ancient Greek sculptor known for his colossal chryselephantine statues. He created the iconic statue of Athena Parthenos in the Parthenon in Athens to restore glory to the city after the Persian invasion. This brought him great fame. However, his close friendship with Pericles later caused problems and he was falsely accused of theft and impiety. He fled to Olympia where he created another famous work, the statue of Zeus, but was later imprisoned on similar charges and died in prison.
Frida Kahlo was a Mexican surrealist painter known for her many self-portraits exploring her identity and troubled marriage. She was disabled by polio as a child and seriously injured in a traffic accident at age 18, after which she began painting during her long recovery. Kahlo painted 151 works, 55 of which were self-portraits, to process her emotional experiences and physical pain. Her paintings combined folk art traditions with surrealist elements to depict personal themes of identity, marriage, and the human experience of suffering.

Breaking Down Walls in Enterprise with Social SemanticsJohn Breslin
Keynote Talk at the Workshop on New Trends in Service Oriented Architecture for massive Knowledge processing in Modern Enterprise (SOA-KME 2012) / Palermo, Italy / 6th July 2012
The document discusses using the concept of "zoom" as a framework for Linked Open Data (LOD). It describes how zoom has been used successfully in digital maps and images to allow users to see varying levels of detail. It proposes that semantic zoom could be applied to LOD to allow users to view data at different levels of semantic completeness and amount of information. Some open questions are also raised about how semantic zoom could best be applied to improve the usability of LOD.

Finally, it describes the main features and architecture of the metaphactory platform for creating and utilizing enterprise knowledge graphs.
Sanderson CNI 2020 Keynote - Cultural Heritage Research Data EcosystemRobert Sanderson
There have been, and continue to be, many initiatives to address the social, technological, financial and policy-based challenges that throw up roadblocks towards achieving this vision. However, it is hard to tell whether we are making progress, or whether we are eternally waiting for the hyperloop that will never come. If we are to ever be able to answer research questions that require a broad, international corpus of cultural data, then we need an ecosystem that can be characterized with 5 “C”s: Collaborative, Consistent, Connected, Correct and Contextualized. Each of these has implications for the sustainability, innovation, usability, timeliness and ethical considerations that must be addressed in a coherent and holistic manner. As with autonomous vehicles, technology (and perhaps even machine “intelligence”) is a necessary but insufficient component.
In this presentation, I will frame and motivate this grand challenge and propose where we can build connections between the academy, the cultural heritage sector, and industry. The discussion will explore the issues, and highlight some of the successful endeavors and more approachable opportunities where, together, progress can be made.
An introduction to the linked.art LOD data model, based on a carefully selected profile of CIDOC-CRM, and expressed as JSON-LD. It focuses on developer happiness and data usability, while trying to also maintain as much of the richness of CRM as possible.
The document discusses the future of repositories and how they may evolve based on emerging technologies and trends. It examines how repositories could adopt aspects of Web 2.0 like social features, tagging, and improved interfaces. It also explores the potential impact of semantic web technologies through richer metadata standards like the Scholarly Works Application Profile (SWAP). The document suggests repositories should focus on making content available on the web rather than just placing it in repositories to better support open access goals.
The document provides an overview of knowledge graphs and introduces metaphactory, a knowledge graph platform. It discusses what knowledge graphs are, examples like Wikidata, and standards like RDF. It also outlines an agenda for a hands-on session on loading sample data into metaphactory and exploring a knowledge graph.
The Europeana Strategy and Linked Open DataDavid Haskiya
The document discusses Europeana's strategy for 2015-2020 and how linked open data and linked open data technologies will help realize this strategy. Key points:
- Europeana's strategy is to transition from metadata to graphs and from strings to things by making data and APIs more linked and open.
- Linked open data allows data from different sources to be combined and helps make content more findable on search engines and in knowledge panels.
- Europeana labs provides APIs, tools, documentation and data to help partners publish linked open data that can be reused in the Europeana portal and other applications.
Talk at 3th Keystone Training School - Keyword Search in Big Linked Data - Institute for Software Technology and Interactive Systems, TU Wien, Austria, 2017
Invited seminar for UIUC's IS 575 class on metadata in theory and practice, about structural metadata practice in RDF/LOD. Touches on OAI-ORE, PCDM, Annotation, IIIF and Linked Art. Challenges explored are graph boundaries, APIs and context specific metadata.
1) The document discusses issues around using 3D models as scholarly resources in publications. It notes that while 3D models are heavily relied upon in virtual heritage publications, few models are actually accessible, usable, or integrated in a way that allows them to be critically evaluated.
2) There is a lack of infrastructure for storing, preserving, and sharing 3D models to support scholarly research. Standards and systems are needed for integrating 3D models and linking them to related scholarly works and resources.
3) Seven steps are proposed to help ensure 3D models can fully support scholarship, such as developing sustainable archives, understanding how to demonstrate research value, and creating robust long-term publication systems.
Introduction to Information Architecture & Design - SVA Workshop 02/15/14Robert Stribley
Events.com is revamping its website to become a leading online resource for attending and promoting events across the United States. During the discovery phase, the information architect conducted user research including surveys and interviews to understand how people learn about and engage with events. A competitive review analyzed other event websites to identify strengths, weaknesses, and opportunities. Personas were then developed based on the research, including Sabrina the party planner, Jerry the out-of-town visitor, Donny the local comedian, and Jenny the professional promoter. In the definition phase, a card sorting activity helped organize events into intuitive categories. The information architect will now use these insights to design the site structure and navigation through techniques like site maps, page types
This document introduces the Linked Art Application Profile, which provides guidelines for describing art objects as structured data using semantic web standards. It describes how the profile takes a progressive enhancement approach, starting with basic human-readable descriptions and moving to more complex machine-readable representations with core entities, unique identifiers, and links between related objects. This enhances interoperability, discovery, and research by allowing data to be aggregated and connected across different cultural heritage institutions on the web.
The explosion in growth of the Web of Linked Data has provided, for the first time, a plethora of information in disparate locations, yet bound together by machine-readable, semantically typed relations. Utilisation of the Web of Data has been, until now, restricted to the members of the community, eating their own dogfood, so to speak. To the regular web user browsing Facebook and watching YouTube, this utility is yet to be realised. The primary factor inhibiting uptake is the usability of the Web of Data, where users are required to have prior knowledge of elements from the Semantic Web technology stack. Our solution to this problem is to hide the stack, allowing end users to browse the Web of Data, explore the information it contains, discover knowledge, and use Linked Data. We propose a template-based visualisation approach where information attributed to a given resource is rendered according to the rdf:type of the instance.

Discussion of cultural heritage issues around usability and prioritization with completeness, and focus on bringing together communities rather than small and transient committees. Focus on Linked Open Usable Data, Annotations, JSON-LD, IIIF and Linked.Art.
Background for linked open data at the J Paul Getty Trust, followed by a summary of Linked Open Usable Data, and an initial walkthrough of the https://linked.art/ model.
The document discusses making linked open data usable. It emphasizes the importance of understanding the audience and their needs when developing linked open data. Key points include knowing the audience, meeting them on their terms, having a conversation to understand their needs, and providing opportunities for meaningful participation. Other tips discussed are focusing on the right abstraction, keeping barriers to entry low, ensuring the data is comprehensible, providing documentation and examples, minimizing exceptions, and designing consistently for JSON-LD. The overall message is that usability must be a central consideration for linked open data to be successful and useful.
This document discusses making linked open data usable. It advocates for publishing and retrieving linked open data through application programming interfaces (APIs) that have the right abstraction level, few barriers to entry, are comprehensible through introspection, and follow consistent patterns. JSON-LD is recommended for expressing linked data through APIs because it separates the data model from the representation using contexts and frames. This allows for usability without compromising semantics. The document also recommends focusing on solving real challenges with available data that meets requirements, and designing data to be reusable by others.
A walkthrough of the CIDOC-CRM based, LOD data model developed and maintained at https://linked.art/ for describing cultural heritage resources and activities.
IIIF and Linked Data: A Cultural Heritage DAM EcosystemRobert Sanderson

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.

Baseline Theory You Need to Know
• Knowledge Graph
A method of managing data by describing entities,
connected via named, semantic relationships into
a coherent network or graph
• Entity
A thing (physical, conceptual, or beyond) of interest
e.g. a physical painting; the concept of oil paint
• Relationship
The way in which two entities are connected
e.g. the painting has a material of oil paint

Interoperability?
• Syntactic Interoperability
In scope! Do the messages passed between client and
server conform to the specifications?
• Semantic Interoperability
In scope! When we use the concept for “painting”
do we mean (approximately) the same thing?
• Single, Unique Identity for each Entity
Out of scope! Multiple representations are necessary,
useful, and important

Design Principles for Usability
1. Scope design through shared use cases
2. Design for international use
3. As simple as possible, but no simpler
4. Make easy things easy, complex things possible
5. Avoid dependency on specific technologies
6. Use REST / Don’t break the web
7. Design for JSON-LD, using LOD principles
8. Follow existing standards & best practices, when possible
9. Don’t fear the network
10. Define success, not failure (for extensibility)

• Consistency across Representations
Each relationship in only one document
• Division of Information across Representations
From the many to the few, and easy to determine

Sidebar on Vocabulary
We typically use Getty’s AAT – Art & Architecture Thesaurus
Terms fall into three categories:
• Required: You must use the term to be considered valid.
Example: “Primary Name”
• Recommended: You should use the term unless there’s a
reason not to. Example: “Painting”
• Listed: You can use the term if you want, no pressure.
Example: “Village”

Partitioning Everywhere
To be more specific about an aspect of some entity, we need
to describe the individual part with that aspect
• A frame is part of a Painting (physical things)
• A digital image is part of a digital document (digital)
• A city is part of a county (place)
• A chapter is part of the full text (language)
• A motif is part of an image (visual)
• A month is part of a year (temporal)
• A concept has a broader concept (types)
• An entity is a member of a collection (set/group membership)

JSON-LD
Linked Art API responses are JSON-LD
• Usability! Developers understand JSON
• Semantics! It’s a full, round-trip-able RDF serialization
• Can treat as a graph or a document or both
Context Document
• Maps JSON keys and values into semantic space
• Linked Art context is stable, breaking changes require a
new major version, so can be aggressively cached

• References are full URIs to ease client processing
• Embedded structures do not have URIs
Context tries to simplify naming to be easier to remember
• No @s, no numbers, no namespaces
• CamelCase classes, snake_case properties

Overall Summary
• Linked Art is a metadata profile that selects appropriate
features of other standards to define a model and set of
web API functionality to implement
• Usability, through consistent and developer friendly
technology choices, is more important than precision and
completeness
• 10 primary classes, several reusable components, a few
class specific patterns to ensure semantic connections
Don’t re-read, just note Usability as core to our principles
They don’t even have different properties! Birth is an event, not an Activity. Production is physical state change, whereas Creation isn’t. The “digital” thing is still somewhat conceptual -- we don’t try to model the physical storage device for example.
