DOIBoost software toolkit 1.0
La Bruzzo S.
Research in information science and scholarly communication strongly relies on the availability of openly accessible datasets of metadata and, where possible, their relative payloads. To this end, CrossRef plays a pivotal role by providing free access to its entire metadata collection, and allowing other initiatives to link and enrich its information. Therefore, a number of key pieces of information result scattered across diverse datasets and resources freely available online. As a result of this fragmentation, researchers in this domain end up struggling with daily integration problems producing a plethora of ad-hoc datasets, therefore incurring in a waste of time, resources, and infringing open science best practices. This software package the spark scripts to generate DOIBoost, a metadata collection that enriches CrossRef with inputs from Microsoft Academic Graph, ORCID, and UnPayWall for the purpose of supporting high-quality and robust research.Project(s): OpenAIRE-Advance

EFG1914 - Documentation of schema mappings and metadata exchange interfaces
Manghi P., La Bruzzo S.
The EFG1914 data infrastructure delivers two main requirements as identified by the user community: i) Single access point to the European movie archives, and ii) High-quality metadata descriptions. These requisites are hindered by the highly heterogeneous nature of the archives. Related problems have been solved through the EFG1914 Common Metadata Model defining a set of eight interrelated entities. In order to better illustrate the model and the relationships it defines among the above entities, this deliverable shows a real-case example about the film "2001: A Space Odyssey" directed by Stanley Kubrik.Source: Project report, EFG19141, Deliverable D6.2, 2013

On bridging data centers and publishers: the data-literature interlinking service
Burton A., Koers H., Manghi P., La Bruzzo S., Aryani A., Diepenbroek M., Schindler U.
Although research data publishing is today widely regarded as crucial for reproducibility and proper assessment of scientific results, several challenges still need to be solved to fully realize its potential. Developing links between the published literature and data sets is one of them. Current solutions are mostly based on bilateral, ad-hoc agreements between publishers and data centers, operating in silos whose content cannot be readily combined to deliver a network connecting research data and literature. The RDA Publishing Data Services Working Group (PDS-WG) aims to address this issue by bringing together different stakeholders to agree on common standards, combine links from disparate sources, and create a universal, open service for collecting and sharing such links: the Data-Literature Interlinking Service. This paper presents the synergic effort of the PDS-WG and the OpenAIRE infrastructure to realize and operate such a service. The Service populates and provides access to a graph of dataset-literature links collected from a variety of major data centers, publishers, and research organizations. At the time of writing, the Service has close to one million links with further contributions expected. Based on feedback from content providers and consumers, PDS-WG will continue to refine the Service data model and exchange format to make it a universal, cross-platform, cross-discipline solution for collecting and sharing dataset-literature links.Source: MTSR 2015 - Metadata and Semantics Research. 9th Research Conference, pp. 324–335, Manchester, UK, 9-11 September 2015

The data-literature interlinking service: towards a common infrastructure for sharing data-article links
Burton A., Koers H., Manghi P., La Bruzzo S., Aryani A., Diepenbroek M., Schindler U.
Purpose Research data publishing is today widely regarded as crucial for reproducibility, proper assessment of scientific results, and as a way for researchers to get proper credit for sharing their data. However, several challenges need to be solved to fully realize its potential, one of them being the development of a global standard for links between research data and literature. Current linking solutions are mostly based on bilateral, ad hoc agreements between publishers and data centers. These operate in silos so that content cannot be readily combined to deliver a network graph connecting research data and literature in a comprehensive and reliable way. The Research Data Alliance (RDA) Publishing Data Services Working Group (PDS-WG) aims to address this issue of fragmentation by bringing together different stakeholders to agree on a common infrastructure for sharing links between datasets and literature. The paper aims to discuss these issues. Design/methodology/approach This paper presents the synergic effort of the RDA PDS-WG and the OpenAIRE infrastructure toward enabling a common infrastructure for exchanging data-literature links by realizing and operating the Data-Literature Interlinking (DLI) Service. The DLI Service populates and provides access to a graph of data set-literature links (at the time of writing close to five million, and growing) collected from a variety of major data centers, publishers, and research organizations. Findings To achieve its objectives, the Service proposes an interoperable exchange data model and format, based on which it collects and publishes links, thereby offering the opportunity to validate such common approach on real-case scenarios, with real providers and consumers. Feedback of these actors will drive continuous refinement of the both data model and exchange format, supporting the further development of the Service to become an essential part of a universal, open, cross-platform, cross-discipline solution for collecting, and sharing data set-literature links. Originality/value This realization of the DLI Service is the first technical, cross-community, and collaborative effort in the direction of establishing a common infrastructure for facilitating the exchange of data set-literature links. As a result of its operation and underlying community effort, a new activity, name Scholix, has been initiated involving the technological level stakeholders such as DataCite and CrossRef.Source: Program (Lond., 1966) 51 (2017): 75–100. doi:10.1108/PROG-06-2016-0048

OAIzer : customized OAI-ORE and OAI-PMH exports of compound objects for the Fedora repository
Bardi A., La Bruzzo S., Manghi P.
Modern Digital Library Systems (DLSs) are based on docu- ment models which surpass the traditional payload-metadata document model to incorporate further entities involved in the research life-cycle. Such DLSs manage graphs of interconnected objects, hence oer tools for the creation, visualization and exports of such graphs. In particular, ob- jects in the graph are exported via standard OAI-ORE and OAI-PMH pro- tocols, encoded as (XML) packages of interlinked information objects", also known as compound objects. Fedora is a well-known repository plat- form, designed to support the realization of DLSs implementing modern document models. To date, Fedora does not provide tools to customize compound object exports from DLS object graphs. This paper presents Fedora-OAIzer, an extension of Fedora which allows DLS developers to customize the structure of compound objects to be exported from a given DLS document model { expressed in terms of Fedora Content Models { and to select the OAI protocol of preference. In order to prove the com- pleteness of the approach, Fedora-OAIzer is compared to other solutions for exporting compound objects from Fedora repositories.Source: Fourteenth International Conference on Grey Literature.

OAIzer: configurable OAI exports over relational databases
La Bruzzo S., Manghi P., Bardi A.
Modern Digital Library Systems (DLSs) typically support information spaces of interconnected objects, whose graph-like document models surpass the traditional DL payload-metadata document models. Examples are repositories for enhanced publications, CRIS systems, cultural heritage archives. To enable interoperability, DLSs expose their objects and interlinks with other objects as "export packages", via standard exchange formats (e.g. XML, RDF encodings) and OAI-ORE or OAI-PMH protocols. This paper presents OAIzer, a tool for the easy configuration and automatic deploy of OAI interfaces over an RDBMSbased DLS. Starting from the given relational representation of a document model, OAIzer provides DLS developers with user interfaces for drafting the intended structure of export packages and the automated deploy of OAI endpoints capable of exporting such packages.Source: MTSR 2013 - Metadata and Semantics Research. 7th Research Conference, pp. 35–47, Thessaloniki, Greece, 19-22 November 2013

This paper presents Fedora-OAIzer, an extension of Fedora which allows DLS developers to customize the structure of compound objects to be exported from a given DLS document model { expressed in terms of Fedora Content Models { and to select the OAI protocol of preference. In order to prove the com- pleteness of the approach, Fedora-OAIzer is compared to other solutions for exporting compound objects from Fedora repositories.Source: GL14 - Fourteenth International Conference on Grey Literature.

A subscription and notification broker for scholarly communication: functionalities and architecture
Artini M., Atzori C., La Bruzzo S.
The OpenAIRE infrastructure services populate and provide access to a graph of objects relative to publications, datasets, people, organizations, projects, and funders aggregated from a variety of data sources. Not only, objects in the graph are harmonized to achieve semantic homogeneity, de-duplicated and merged, and enriched by inference with missing properties and/or relationships. The OpenAIRE Literature Broker Service is designed to offer subscription and notification functionalities for institutional repositories to: (i) learn about publication objects in OpenAIRE that do not appear in their collection but may be pertinent to it, and (ii) learn about extra properties or relationships relative to publication objects in their collection. Due to the high variability of the information space the following problems may arise: (i) subscriptions may vary over time to adapt to information space evolution, (ii) repository managers need to be able to quickly test their configurations before activating them, (iii) notifications may be redundant, and (iv) notifications may be very large over time. This paper presents the data model and software architecture of the OLBS, specifically designed to address these issues.Source: ISTI Technical reports, 2016

The OpenAIRE action manager framework
Artini M., Atzori C., La Bruzzo S.
The OpenAire infrastructure offers services for collecting records (publications, datasets, persons, organizations, data sources, projects) from external data sources with the purpose of identifying relationships between them. The collected objects and their relationships are stored in HBASE according to the OpenAIRE data model. The Action Manager framework has been designed to offer an OpenAIRE data model oriented API for the enrichment and the fixing of the OpenAIRE HBASE information space.Source: ISTI Technical reports, 2014

OpenAIRE APIs for data access to third party services
Artini M., Atzori C., Dell'Amico A., Labruzzo S.
The OpenAIRE infrastructure services populate and provide access to a graph of objects relative to publications, datasets, people, organizations, projects, and funders aggregated from a variety of data sources. Not only, objects in the graph are harmonized to achieve semantic homogeneity, de-duplicated and merged, and enriched by inference with missing properties and/or relationships. The aim of this technical report is to describe to third-party service managers (developers in the need of accessing data) how the OpenAIRE information space can be accessed and according to which combination of protocol and format. The document is organized according to a data centric view, where managers should first identify the typology of data they would like to access, and then verify which protocols and formats are available.Source: ISTI Technical reports, 2014

Customized OAI-ORE and OAI-PMH exports of compound objects for the Fedora repository
Bardi A., La Bruzzo S., Manghi P.
Modern Digital Library Systems (DLSs) are based on docu- ment models which surpass the traditional payload-metadata document model to incorporate further entities involved in the research life-cycle. Such DLSs manage graphs of interconnected objects, hence oer tools for the creation, visualization and exports of such graphs. In particular, ob- jects in the graph are exported via standard OAI-ORE and OAI-PMH pro- tocols, encoded as (XML) packages of interlinked information objects", also known as compound objects. Fedora is a well-known repository plat- form, designed to support the realization of DLSs implementing modern document models. To date, Fedora does not provide tools to customize compound object exports from DLS object graphs. This paper presents Fedora-OAIzer, an extension of Fedora which allows DLS developers to customize the structure of compound objects to be exported from a given DLS document model { expressed in terms of Fedora Content Models { and to select the OAI protocol of preference. In order to prove the com- pleteness of the approach, Fedora-OAIzer is compared to other solutions for exporting compound objects from Fedora repositories.Source: Fourteenth International Conference on Grey Literature.

OpenAIRE's DOIBoost - Boosting Crossref for Research
La Bruzzo S., Manghi P., Mannocci A.
Research in information science and scholarly communication strongly relies on the availability of openly accessible datasets of scholarly entities metadata and, where possible, their relative payloads. Since such metadata information is scattered across diverse, freely accessible, online resources (e.g. Crossref, ORCID), researchers in this domain are doomed to struggle with (meta)data integration problems, in order to produce custom datasets of often undocumented and rather obscure provenance. This practice leads to waste of time, duplication of efforts, and typically infringes open science best practices of transparency and reproducibility of science. In this article, we describe how to generate DOIBoost, a metadata collection that enriches Crossref with inputs from Microsoft Academic Graph, ORCID, and Unpaywall for the purpose of supporting high-quality and robust research experiments, saving times to researchers and enabling their comparison. To this end, we describe the dataset value and its schema, analyse its actual content, and share the software Toolkit and experimental workflow required to reproduce it. The DOIBoost dataset and Software Toolkit are made openly available via Zenodo.org. DOIBoost will become an input source to the OpenAIRE information graph.Source: IRCDL 2019 - Italian Research Conference on Digital Libraries, pp. 133–143, Pisa, Italy, 31/01/2019, 01/2/2019

DOIBoost Dataset Dump

Research in information science and scholarly communication strongly relies on the availability of openly accessible datasets of metadata and, where possible, their relative payloads. To this end, CrossRef plays a pivotal role by providing free access to its entire metadata collection, and allowing other initiatives to link and enrich its information. Therefore, a number of key pieces of information result scattered across diverse datasets and resources freely available online. As a result of this fragmentation, researchers in this domain end up struggling with daily integration problems producing a plethora of ad-hoc datasets, therefore incurring in a waste of time, resources, and infringing open science best practices. DOIBoost is a metadata collection that enriches CrossRef with inputs from Microsoft Academic Graph, ORCID, and Unpaywall for the purpose of supporting high-quality and robust research experiments, saving times to researchers and enabling their comparison.Project(s): OpenAIRE-Advance
