This document discusses using semantic web and linked data principles to improve traceability in supply chains. It proposes a framework that uses GS1 standards like EPCIS and EPC to generate linked pedigrees from event data. Ontologies are developed to represent traceability data and processes. Extract, transform, and load processes are used to publish relational EPCIS data as linked open data. This allows traceability information to be interlinked and shared across supply chain partners.
Building linked data large-scale chemistry platform - challenges, lessons and...Valery Tkachenko
Ā
Chemical databases have been around for decades, but in recent years we have observed a qualitative change from rather small in-house built proprietary databases to large-scale, open and increasingly complex chemistry knowledgebases. This tectonic shift has imposed new requirements for database design and system architecture as well as the implementation of completely new components and workflows which did not exist in chemical databases before. Probably the most profound change is being caused by the linked nature of modern resources - individual databases are becoming nodes and hubs of a huge and truly distributed web of knowledge. This change has important aspects such as data and format standards, interoperability, provenance, security, quality control and metainformation standards.
ChemSpider at the Royal Society of Chemistry was first public chemical database which incorporated rigorous quality control by introducing both community curation and automated quality checks at the scale of tens of millions of records. Yet we have come to realize that this approach may now be incomplete in a quickly changing world of linked data. In this presentation we will talk about challenges associated with building modern public and private chemical databases as well as lessons that we have learned from our past and present experience. We will also talk about solutions for some common problems.

The Open PHACTS project delivers an online platform integrating a wide variety of data from across chemistry and the life sciences and an ecosystem of tools and services to query this data in support of pharmacological research, turning the semantic web from a research project into something that can be used by practising medicinal chemists in both academia and industry. In the summer of 2015 it was the first winner of the European Linked Data Award. At the Royal Society of Chemistry we have provided the chemical underpinnings to this system and in this talk we review its development over the past five years. We cover both our early work on semantic modelling of chemistry data for the Open PHACTS triplestore and more recent work building an all-purpose data platform, for which the Open PHACTS data has been an important test case, what has worked well, what's missing and where this is is likely to go in future.
FAIR Computational Workflows
Computational workflows capture precise descriptions of the steps and data dependencies needed to carry out computational data pipelines, analysis and simulations in many areas of Science, including the Life Sciences. The use of computational workflows to manage these multi-step computational processes has accelerated in the past few years driven by the need for scalable data processing, the exchange of processing know-how, and the desire for more reproducible (or at least transparent) and quality assured processing methods. The SARS-CoV-2 pandemic has significantly highlighted the value of workflows.
This increased interest in workflows has been matched by the number of workflow management systems available to scientists (Galaxy, Snakemake, Nextflow and 270+ more) and the number of workflow services like registries and monitors. There is also recognition that workflows are first class, publishable Research Objects just as data are. They deserve their own FAIR (Findable, Accessible, Interoperable, Reusable) principles and services that cater for their dual roles as explicit method description and software method execution [1]. To promote long-term usability and uptake by the scientific community, workflows (as well as the tools that integrate them) should become FAIR+R(eproducible), and citable so that authorās credit is attributed fairly and accurately.
The work on improving the FAIRness of workflows has already started and a whole ecosystem of tools, guidelines and best practices has been under development to reduce the time needed to adapt, reuse and extend existing scientific workflows. An example is the EOSC-Life Cluster of 13 European Biomedical Research Infrastructures which is developing a FAIR Workflow Collaboratory based on the ELIXIR Research Infrastructure for Life Science Data Tools ecosystem. While there are many tools for addressing different aspects of FAIR workflows, many challenges remain for describing, annotating, and exposing scientific workflows so that they can be found, understood and reused by other scientists.
This keynote will explore the FAIR principles for computational workflows in the Life Science using the EOSC-Life Workflow Collaboratory as an example.

Fostering Business and Software Ecosystems for large-scale Uptake of IoT in F...Sjaak Wolfert
Ā
The Internet of Things (IoT) is expected to be a real game changer that will drastically improve productivity and sustainability in food and farming. However, current IoT applications in this domain are still fragmentary and mainly used by a small group of early adopters. The Internet of Food and Farm 2020 Large-Scale Pilot (IoF2020) addresses the organizational and technological challenges to overcome this situation by fostering a large-scale uptake of IoT in the European food and farming domain. The heart of the project is formed by a balanced set of multi-actor trials that reflect the diversity of the food and farming domain. Each trial is composed of well-delineated use cases developing IoT solutions for the most relevant challenges of the concerned subsector. The project conducts 5 trials with a total of 19 use cases in arable, dairy, fruits, vegetables and meat production. IoF2020 embraces a lean multi-actor approach that combines the development of Minimal Viable Products (MVPs) in short iterations with the active involvement of various stakeholders. The architectural approach supports interoperability of multiple use case systems and reuse of IoT components across them. Use cases are also supported in developing business and solving governance issues. The IoF2020 ecosystem and collaboration space is established to boost the uptake of IoT in Food and Farming and pave the way for new innovations.
Urban sustainability and food security in africa and china. ottawa conference...Chijioke J. Evoh, Ph.D.
Ā
This paper explores urban food security within the context of development cooperation between China and sub-Saharan African countries. Recently, development cooperation between China and African countries has grown in different dimensions. Within Sino-African relations framework, little efforts have been made to share development knowledge on urban food security in the context of rapid urbanization. Chinese and African cities share two commonalties: the increasing trend of urbanization and the continuous existence of subsistent agriculture, particularly in the rural areas. Chinese cities have managed to create a sustainable system of urban food security for their teeming population. This study focuses on urban food planning in key Chinese cities such as Beijing, Shanghai, Guangzhou, and Shenzhen. Food situations in these cities will be compared with what obtains in African cities such as Lagos, Accra and Lilongwe. This study argues for a complementary two-way learning process between African cities and their counterparts in China on urban food policy and citizens-driven urban food planning. Chinese and African cities can share some policy lessons on food policy and governance.
What policy lessons can African cities learn from China on the implementation of effective urban food policy? Descriptive methods are used to critically analyze the urban food situation in these regions. This includes the use of primary data on food security situation in urban areas. Besides, secondary data and a desk review of existing published and grey literature are used. National and regional dynamics of food production, distribution and consumption would be triangulated for a comprehensive assessment.

I presented work from all 3 phases of the FI-PPP program and how we started this from projects in The Netherlands.
Entrepreneurs active in the agricultural sector spend more and more of their time registering and publishing all kinds of data, as the government, certification bodies, banks, clients, the retail sector and consumers all want to have more insight into how safe and sustainable their food is.
The majority of this agriculture-related data is still paper-based, spread over different systems and difficult to exchange between the people who want to access it. This is why digitising agricultural business data is an important item on the agenda. With FarmDigital, we can respond to these developments.
FarmDigital is an action research programme which is currently working towards a situation in which data only needs to be entered once and can be shared easily. It aims to achieve this goal by standardising data and developing and implementing an independent, digital platform for people to use.

Smart Farming is a development that emphasizes the use of information and communication technology in the
cyber-physical farm management cycle. New technologies such as the Internet of Things and Cloud Computing
are expected to leverage this development and introduce more robots and artificial intelligence in farming.
This is encompassed by the phenomenon of Big Data, massive volumes of data with a wide variety that can be
captured, analysed and used for decision-making. This review aims to gain insight into the state-of-the-art of
Big Data applications in Smart Farming and identify the related socio-economic challenges to be addressed. Following
a structured approach, a conceptual framework for analysiswas developed that can also be used for future
studies on this topic. The review shows that the scope of Big Data applications in Smart Farming goes beyond
primary production; it is influencing the entire food supply chain. Big data are being used to provide predictive
insights in farming operations, drive real-time operational decisions, and redesign business processes for
game-changing business models. Several authors therefore suggest that Big Data will cause major shifts in
roles and power relationsamong different players in current food supply chain networks. The landscape of stakeholders
exhibits an interesting gamebetween powerful tech companies, venture capitalists and often small startups
and new entrants. At the same time there are several public institutions that publish open data, under the
condition that the privacy of persons must be guaranteed. The future of Smart Farming may unravel in a continuum
of two extreme scenarios: 1) closed, proprietary systems in which the farmer is part of a highly integrated
food supply chain or 2) open, collaborative systems inwhich the farmer and every other stakeholder in the chain
network is flexible in choosing business partners as well for the technology as for the food production side. The
further development of data and application infrastructures (platforms and standards) and their institutional
embedment will play a crucial role in the battle between these scenarios. From a socio-economic perspective,
the authors propose to give research priority to organizational issues concerning governance issues and suitable
business models for data sharing in different supply chain scenarios.

This paper surveys the landscape of linked open data projects in cultural heritage, exam- ining the work of groups from around the world. Traditionally, linked open data has been ranked using the five star method proposed by Tim Berners-Lee. We found this ranking to be lacking when evaluating how cultural heritage groups not merely develop linked open datasets, but find ways to used linked data to augment user experience. Building on the five-star method, we developed a six-stage life cycle describing both dataset development and dataset usage. We use this framework to describe and evaluate fifteen linked open data projects in the realm of cultural heritage.

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.

Observations: Data sharing in supply chains
Existing mechanisms for sharing data and information
along supply chains are highly restricted and extremely
complex.
There is a lack of information models that facilitate the
exchange of end-to-end supply chain product and process
knowledge.
There is a very conservative āneed-to-knowā attitude such
that essentially information flows only āone-up, one downā.

6. Motivation GS1, 7th November 2014, London
Observations: Data sharing in supply chains
Traceability datasets curated by partners are inherently
related, however the varied underlying schemas lead to
mapping overheads and interoperability issues.
The semantics of traceability data and data curation
processes are informally defined in
specifications/standards and associated implementations.
Lack of a systematic and standardised way to exchange
traceability information.
Large volumes of traceability data are recorded at each partnerās end.

Semantic Web in 1 slide
Web scale data ! Machines first!
Marks a shift in thinking from publishing data on the Web as
human readable, interlinked HTML documents to publishing
self describing, interlinked data on the Web in
āmachine-interpretableā formats.
self describing: associating metadata with data via
vocabularies/ontologies/data dictionaries.
interlinked data: āmeaningfulā links between āpiecesā of self
described data.
machine-interpretable: an underlying model for data that
enables the exploitation of computational power to
automate and improve certain tasks at Web (Big data)
scale e.g. Search, data integration, visualisations and
more...

Semantic Web: The W3C Technology stack
HTTP URIs - universal identifiers for resources on the Web.
RDF data model - a ātriplesā based model.
RDFS and OWL - domain knowledge representation
standards that enable inferencing over asserted facts.
SPARQL - a query language for datasets encoded using
the RDF data model.

16. Semantic Web Linked Data GS1, 7th November 2014, London
HTTP URIs
In order to publish data on the Web, resources, i.e., items
in the dataset and their relationships must be uniquely
identified.
HTTP URIs provide a simple way to create globally unique
names in a decentralised manner.
Besides identifying resources uniquely, they also serve as
a means to access further information about the resources.

RDF: Resource Description Framework
RDF is a data model.
Basic building block: a triple, a statement
A triple is composed of:
subject predicate (property) object
Each RDF Triple is a complete and unique fact.
Abstract data model with several concrete syntaxes.
Most common informal syntax: Directed Graph
Most common formal syntaxes: Turtle, RDF/XML

SPARQL: Querying RDF datasets
SPARQL is a syntactically-SQL-like language for
querying RDF datasets via pattern matching.
SPARQL queries contain a set of triple patterns called a
basic graph pattern (BGP).
Triple patterns are like RDF triples except that each of the
subject, predicate and object may be a variable.
A BGP matches a subgraph of the RDF data when RDF
terms from that subgraph may be substituted for the
variables.

Pedigrees
Most widely prevalent in the pharmaceutical industry.
Pedigree (e-pedigree) is an audit trail that records the path
and ownership of a drug as it moves through the supply
chain.
Each stakeholder involved in the manufacture or
distribution of the drug adds information to the pedigree.

EEM: EPCIS Event Model
Data visibility (tracking and tracing) in supply chains has
received considerable attention in recent years.
EEM based linked datasets can be exploited in order to
improve visibility, accuracy and automation along the
supply chain.
EEM along with CBVVocab can be used to derive implicit
knowledge that can expose inefficiencies such as shipment
delay, inventory shrinkage and out-of-stock situation.

74. Summary GS1, 7th November 2014, London
Linked Pedigrees
Semantic Web standards, ontologies and linked data can
be utilised to record and represent real time supply chain
knowledge via ālinked pedigreesā.
EEM forms the basis for traceability in supply chains -
Event-based Linked Pedigrees.
Complex Event Processing over continuous streams of
semantically interlinked EPCIS event datasets enable
automated generation of linked pedigrees, detection of
exceptions and validation of integrity constraints.
The proposed approach is domain independent and can
be widely applied to most scenarios of traceability as long
as there is conformance to EPCIS 1.1 in the supply chain.
