This document discusses the necessity of semantic representation in electronic laboratory notebooks (ELNs) to enhance data sharing and comparability in chemistry. It outlines various ontologies and frameworks (such as RDF and JSON-LD) that facilitate the structured representation of scientific data and metadata. The paper emphasizes the need for a global research network that standardizes data sharing practices and supports comprehensive scientific data representation.

- 3. “Big Data” and the “Semantic Web” are the current buzz words du jour but what do they mean for chemistry? Lots of heterogeneous data and metadata with even more “semantic” data to represent it Look at what we want rather that what we have… We went chemical data that is: Easy to share, find, and compare Freely available but with provenance Globally sourced and without IP restrictions on reuse Utopia: A Global Research Network
- 4. An electronic way to record data… ...equivalent to a laboratory notebook But ELN’s should not be thought of so lowly... An ELN must:* Keep track of research data Reference resources used in research and… …capture the story of research What is an Electronic Laboratory Notebook? * Insight from Tony Williams
- 5. The interface should mirror a laboratory notebook Behind the scenes though it should use state of the art software, data formats, data/metadata practices, and web technologies to manage data generation, workflows, remote data access, authentication etc… As a result it needs to speak the same language as other data sources and store data in a format that others can read and reuse Foundational building block of a Global Research Network What should an ELN be?
- 6. Semantics is the study of meaning -> We need to give meaning to what is created in an ELN Described in computers using the Resource Description Framework (RDF) which: Makes statements about objects… … their relationships to other objects... ...using subject-predicate-object “triples” RDF allows knowledge representation Meaning is represented by using one or more ontologies The Semantics of Semantics

The Healthcare and Life Science (HCLS) Community Profile is a Note from the Semantic Web HCLS Interest Group Access to consistent, high-quality metadata is critical to finding, understanding, and reusing scientific data. This document describes a consensus among participating stakeholders in the Health Care and the Life Sciences domain on the description of datasets using the Resource Description Framework (RDF). This specification meets key functional requirements, reuses existing vocabularies to the extent that it is possible, and addresses elements of data description, versioning, provenance, discovery, exchange, query, and retrieval.

- 24. A lot exists to semantically represent the scientific process that can be leveraged as part of an ELN system A data standard needs to be agreed upon Agreeing on implementation standards will take time because of size of user community Integration and coverage of ontologies will be necessary to fully implement a system that underpins a Global Research Network Domain specific knowledge representation needed in many areas Take Home
