Reinventing Laboratory Data To Be Bigger, Smarter & Faster
• Big Data technologies, especially Data Lakes are spreading across many industries at the moment with the hopes that they will provide unprecedented capabilities for data integration and data analytics
• In spite of the popularity and promise of these technology approaches, many early adopters are not seeking immediate solutions to their complex problems. Answers are not simply appearing – this talk will explore this issue more thoroughly
• Of the 4 V’s of Big Data, Data Variety and Data Veracity (uncertainty) are of increasing importance. These can cause barriers to successful integration strategies , which, in turn, can lead to poorly performing analytics.
• The problems of Variety and Veracity can be tackled using a new form of Data Science which combines formal ontologies with statistical heuristics. This talk will explore some key features of these approaches and how they can be developed together in symbiosis – leading to complex models that allow for improved analytics – or as we call it Big Analysis.
• The end result is improved capture of data types/sources, from laboratory instrument data, to clinical data, to regulatory rules & submissions, all the way to business drivers for the enterprise. In the end providing advanced analytics capabilities that can be built as modules and expand across an enterprise.

Metadata Standards
This document discusses standards and metadata. It defines a standard as a document that provides requirements to ensure materials are fit for their purpose. Metadata is defined as "data about data" that describes other data. The document outlines several important metadata standards like Dublin Core, MARC, EAD, MODS and RDF. It provides details on the purpose and specifications of these standards, noting they are used to enhance accessibility, discovery and preservation of information.
Data repositories -- Xiamen University 2012 06-08
The document discusses data repositories and services. It begins by defining what a data repository is, noting that it is a logical and sometimes physical partitioning of data where multiple databases reside. It then outlines some key aspects of data repositories, including technical features like standards, software, and staffing requirements. The document also discusses functions of repositories like content management, archiving, dissemination and system maintenance. It provides examples of institutional repositories and data repositories, highlighting characteristics of each. Finally, it provides a case study on Dryad, an international repository for data and publications in biosciences.
How Portable Are the Metadata Standards for Scientific Data?
The one-covers-all approach in current metadata standards for scientific data has serious limitations in keeping up with the ever-growing data. This paper reports the findings from a survey to metadata standards in the scientific data domain and argues for the need for a metadata infrastructure. The survey collected 4400+ unique elements from 16 standards and categorized these elements into 9 categories. Findings from the data included that the highest counts of element occurred in the descriptive category and many of them overlapped with DC elements. This pattern also repeated in the elements co-occurred in different standards. A small number of semantically general elements appeared across the largest numbers of standards while the rest of the element co-occurrences formed a long tail with a wide range of specific semantics. The paper discussed implications of the findings in the context of metadata portability and infrastructure and pointed out that large, complex standards and widely varied naming practices are the major hurdles for building a metadata infrastructure.
DCW Data Quality 1992
This document discusses two approaches to incorporating data quality statements into spatial databases. It describes the Vector Product Format (VPF) used by the Digital Chart of the World project, which contains data quality information at different levels to allow users to evaluate data utility. VPF includes seven types of data quality information such as source, positional accuracy, and logical consistency. The document also discusses guidelines from the International Cartographic Association to provide a consistent approach to assessing data quality.
Hdg geo discussion
This document discusses a potential new HDF profile called HDF-GEO that would incorporate lessons learned from Earth science data formats. It proposes hosting a discussion at the HDF workshop to discuss the need, scope, and direction for HDF-GEO. The discussion would involve getting input from Earth science practitioners on their data needs and the successful features of existing formats. Key questions are posed around what a profile is, how it relates to standards, and what level of standardization would be useful versus overkill. The goal would be to establish best practices to support geo-referenced and time-series Earth science data.

Revolutionizing Laboratory Instrument Data for the Pharmaceutical Industry:...
The Allotrope Foundation is a consortium of major pharmaceutical companies and a partner network whose goal is to address challenges in the pharmaceutical industry by providing a set of public, non-proprietary standards for using and integrating analytical laboratory data. Current challenges in data management within the pharmaceutical industry often center around inconsistent or incomplete data and metadata and proprietary data formats. Because of a lack of standardization, several operations (e.g. integration of instruments/applications, transfer of methods or results, archiving for regulatory purposes) require unnecessary efforts. Further, higher level aggregation of data, e.g. regulatory filings, that are derived from multiple sources of laboratory data are costly to create. These unnecessary costs impact operations within a company’s laboratories, between partnering companies, and between a company and contract research organizations (CROs). Finally, the accelerating transition of laboratories from hybrid (paper + electronic) to purely electronic data streams, coupled with an ever-increasing regulatory scrutiny of electronic data management practices, further require a comprehensive solution. This talk will discuss how The Allotrope Foundation is providing a new framework for data standards through collaboration between numerous stakeholders.
AnIML: A New Analytical Data Standard
Started in 2004 (under ASTM Committee E13.15) the Analytical Information Markup Language (AnIML) is an XML based standard for capturing, sharing, viewing, and archiving analytical instrument data from any analytical technique.
This paper discusses the AnIML standard in terms of philosophy, structure, usage, and the resources available to work with the standard. Examples will be given for different techniques as well as strategies for migration of legacy data. Finally, the current status of the standard and time frame for promulgation through ASTM will be reported.

Advantages and disadvantages
Trends and Current Issues
Future Research Possibilities
Anthony J brookes
This document discusses knowledge engineering for health and big data. It notes that the rate of data generation is changing but complexity, requirement to use data, and mass of useless data are stable. Knowledge engineering was first defined in 1983 as integrating knowledge into computer systems to solve complex problems. The document discusses building a knowledge engineering community and notes a need for standards around semantics, syntax, technology, and quality. It advocates for a knowledge extraction approach rather than data warehouses and discusses architectural concepts, policy and strategy considerations, and acknowledges GEN2PHEN partners and funding sources.
Dataset description: DCAT and other vocabularies
This document discusses metadata needed to describe datasets for applications to find and understand them when stored in data catalogs or repositories. It examines existing dataset description vocabularies like DCAT and their limitations in fully capturing necessary metadata.
Key points made:
- Machine-readable metadata is important for datasets to be discoverable and usable by applications when stored across repositories.
- Metadata should describe the dataset, distributions, dimensions, semantics, protocols/APIs, subsets etc.
- Vocabularies like DCAT provide some metadata but don't fully cover dimensions, semantics, protocols/APIs or subsets.
- No single vocabulary or data catalog solution currently provides all necessary metadata for full semantic interoperability.
Harmonization of HDF with National Imagery Transfer Format (NITF) 2.1
Harmonization of HDF with National Imagery Transfer Format (NITF) 2.1The HDF-EOS Tools and Information Center
HDF5 has already demonstrated its ability to adapt to diverse applications, and to integrate with other standards, e.g., netCDF. The National Imagery Transfer Format (NITF) is another format which might benefit from HDF5 as it evolves.
NITF is the mandated standard for formatting digital imagery and imagery-related products, and exchanging them among the DoD and a number of US government agencies.
Although NITF has been improved over the years, and although designed to be extensible, there are technical and conceptual limits to its original paradigm: mono- and polychromatic images, symbols, text and associated data. NITF has been a mandated standard for many years, and enterprise architectures have been built around it. There are important reasons why it should be retained.
New sensors and algorithms are at the verge of stressing the standard with multispectral, hyperspectral, extended response, variable scale, time series, radar, video, and multisensor fusion products. Metadata are becoming more complex as the need for annotation and supporting data grows. Some imagery-like products are already originated in HDF, and others would benefit from a flexible format such as HDF.
Portions of the NITF user community are exploring ways to move beyond its limits, to incorporate enhanced metadata, and to set procedures for suitable product profiles. This presentation develops a mapping between HDF5 and NITF structures and features. It concludes with some ideas on how NITF could be extended by harmonization with HDF5, while affording minimal disruption to operational uses.Where is the opportunity for libraries in the collaborative data infrastructure?

NISO Webinar: Metadata for Preservation: A Digital Object's Best Friend
NISO Webinar: Metadata for Preservation: A Digital Object's Best Friend National Information Standards Organization (NISO)
Over the past decade, as the scholarly community’s reliance on e-content has increased, so too has the development of preservation-related digital repositories. The need for descriptive, administrative, and structural metadata for each digital object in a preservation repository was clearly recognized by digital archivists and curators. However, in the early 2000’s, most of the published specifications for preservation-related metadata were either implementation specific or broadly theoretical. In 2003, the Online Computer Library Center (OCLC) and Research Libraries Group (RLG) established an international working group called PREMIS (Preservation Metadata: Implementation Strategies) to develop a common core set of metadata elements for digital preservation. The first version of the PREMIS Data Dictionary for Preservation Metadata and its supporting XML schema was issued in 2005. Experience using its specifications in preservation repositories has led to several revisions, with the completion of a version 2.0 in 2008. The Data Dictionary is now in version 2.2 (July 2012), and it is widely implemented in preservation repositories throughout the world in multiple domains.Applying Digital Library Metadata Standards

Metadata For Preservation Delos
This document discusses preservation metadata, which supports the long-term preservation of digital objects. It outlines common types of preservation metadata like fixity, viability, renderability, and authenticity data. Standards for preservation metadata are also examined, including PREMIS and METS, which define the core metadata needed to document digital preservation processes. Issues around implementing preservation metadata schemas and ensuring interoperability are also considered.
Graphic standards and exchange formats
The document discusses graphics standards and the need for data exchange standards when transferring CAD files between different software and hardware platforms. It covers early issues with hardware dependence and the development of device-independent standards like GKS. It also summarizes several important neutral CAD data exchange standards, including DXF, IGES, STEP, and discusses some of their limitations in fully transferring design intent and parametric models. It proposes a macro-parametric approach using standardized modeling commands to improve the exchange of CAD files while maintaining parametric design histories.
Cad cam
Computers are used extensively in two main categories of industrial manufacturing applications: 1) direct computer monitoring and control of manufacturing processes, and 2) various manufacturing support functions through tools like CAD, CAM, CAPP and more. CAD software allows designing digital models of products while CAM software generates CNC programs for machining. Other support functions include planning, quality control and testing. Computers have transformed manufacturing by automating processes and supporting all stages from design to production.
