Technologies

The information model of URIS RAS is based on Semantic Web – RDF, RDFS, OWL ontology of scientific information. This includes:

• Scientific activity, in particular projects as a process, conferences, seminars etc.

• Participants of Scientific activity, like persons, working groups, organizations etc.

• Results of Scientific activity, like data bases, software projects, innovations etc.

• Documents and publications, like papers, dissertations etc

21/04/23 14

URIS Metadata requirements

•Include basic resource types•Provide access to resources•Provide extensibility•Provide data integration•Provide identification•Provide searching in distributed environment•Use Semantic Web approach.•Provide interoperobility

21/04/23 15

URIS Metadata standards

Semantic Web – RDF, RDFS, OWL DCMI - Dublin Core Metadata Initiative (dublincore.org)

PRISM - Publishing Requirements for Industry Standard Metadata (Adobe,…)

AGLS Metadata Standard

RAS institutions information tasks

• Inner administrative tasks• Institution as a research RAS

organization• Support of a research process• Public representation

21/04/23 18

The software package“RAS Institution”

The software package “The RAS Institution” is intended to supply institutions with a modern information system that supports internal requirements (publication of scientific information, administrative processes and information etc.) from one hand, and external ones (representation of the information in URIS RAS and Internet) from another hand. It includes:

Infrastructure services that supports

•Data storage

•Global identification

•Data exchange and replication

•Security

•Indexing and search.

21/04/23 19

The software package“RAS Institution”

Base components include subsystems

•Administrative directory

•Publications

•Projects.

•Interaction components

•News

•Forums

•Private communication

•Application components

•Publishing department

GeoMeta portal

21/04/23 31

Purposes– Metadata support (keeping and

editing)– Metadata harvesting– Integration of scientific spatial data– Searching of spatial data and

services– Spatial data visualisation (maps,

pictuers etc)

21/04/23 32

Architecture

• Implementation is based on RAS Institution

• Based on ISO 19115/19139 standards

21/04/23 33

GeoMeta Functionality• In addition to main URIS resources

(person, publication, organization, project) the system supports spatial data

• Main functions:– Resource cataloging, harvesting, loading,

searching;– Keeping spatial data in a repository and

access to these data;– Access via standard protocols (WFS, WMS);– Data (maps) visualization;– Directories management.

Protected Sites Information System

21/04/23 37

Information system on protected sites

• Is based on GeoMeta

• Functionality– Data model is based on ISO ISO

19101 Reference model, 9109 Rules for Application Schema, INSPIRE

– Loading data– Navigation, searching– Queries

21/04/23 38

ProposalsThe integration of scientific data in the

common scientific information space, the integration of this space with a distributed system of scientific digital libraries.

The challenge is to develop formalisms, methods of implementation and a pilot implementation, particularly:

21/04/23 39

Proposals

• Ontologies for some scientific domains. Science is big, so the claim to universal coverage is not realistic. Therefore, we should focus on specific subject areas, such as spatial data, for which there are well-developed standards for describing and organizing data.

21/04/23 40

Proposals

The formal means of data integration based on domain ontologies. The integration in particular, should include data binding, i.e. linkages based on the data identification.

21/04/23 41

Proposals

• Creating key information (metadata) in storing it in special (data) centers, in particular, information about the relationships between data.

21/04/23 42

Proposals

• Establishment of protocols that work with distributed information, in particular, searching.

21/04/23 43

Proposals

• Development of means for extracting information from sources and loading appropriate meta information into the global environment (storage centers).

21/04/23 44

Proposals

• Development of user interfaces in the format of digital libraries, ie, digital libraries, working with the metadata of the global environment and having the ability to extract data from sources.
