Documentación en Arqueología. Aplicaciones del Núcleo Español de Metadatos

RESUMEN Las aplicaciones de los Sistemas de Información Geográfica (SIG) a la Arqueología, u otra disciplina humanística no son una novedad. La evolución de los mismos hacia sistemas distribuidos e interoperables, y estructuras donde las políticas de uso, compartido y coordinado de los datos sí lo son, estando todos estos aspectos contemplados en la Infraestructura de Datos Espaciales. INSPIRE es el máximo exponente europeo en cuestiones de iniciativa y marco legal en estos aspectos. La metodología arqueológica recopila y genera gran cantidad de datos, y entre los atributos o características intrínsecas están la posición y el tiempo, aspectos que tradicionalmente explotan los SIG. Los datos se catalogan, organizan, mantienen, comparten y publican, y los potenciales consumidores comienzan a tenerlos disponibles. Toda esta información almacenada de forma tradicional en fichas y posteriormente en bases de datos relacionadas alfanuméricas pueden ser considerados «metadatos» en muchos casos por contener información útil para más usuarios en los procesos de descubrimiento, y explotación de los datos. Además estos datos también suelen ir acompañados de información sobre ellos mismos, que describe su especificaciones, calidad, etc. Cotidianamente usamos los metadatos: ficha bibliográfica del libro o especificaciones de un ordenador. Pudiéndose definir como: «información descriptiva sobre el contexto, calidad, condición y características de un recurso, dato u objeto que tiene la finalidad de facilitar su recuperación, identificación,evaluación, preservación y/o interoperabilidad». En España existe una iniciativa para estandarizar la descripción de los metadatos de los conjuntos de datos geoespaciales: Núcleo Español de Metadatos (NEM), los mismos contienen elementos para la descripción de las particularidades de los datos geográficos, que incluye todos los registros obligatorios de la Norma ISO19115 y del estudio de metadatos Dublin Core, tradicionalmente usado en contextos de Biblioteconomía. Conscientes de la necesidad de los metadatos, para optimizar la búsqueda y recuperación de los datos, se pretende formalizar la documentación de los datos arqueológicos a partir de la utilización del NEM, consiguiendo así la interoperabilidad de la información arqueológica. SUMMARY The application of Geographical Information Systems (GIS) to Archaeology and other social sciences is not new. Their evolution towards inter-operating, distributed systems, and structures in which policies for shared and coordinated data use are, and all these aspects are included in the Spatial Data Infrastructure (SDI). INSPIRE is the main European exponent in matters related to initiative and legal frame. Archaeological methodology gathers and creates a great amount of data, and position and time, aspects traditionally exploited by GIS, are among the attributes or intrinsic characteristics. Data are catalogued, organised, maintained, shared and published, and potential consumers begin to have them at their disposal. All this information, traditionally stored as cards and later in relational alphanumeric databases may be considered «metadata» in many cases, as they contain information that is useful for more users in the processes of discovery and exploitation of data. Moreover, this data are often accompanied by information about themselves, describing its especifications, quality, etc. We use metadata very often: in a book’s bibliographical card, or in the description of the characteristics of a computer. They may be defined as «descriptive information regarding the context, quality, condition and characteristics of a resource, data or object with the purpose of facilitating is recuperation, identification, evaluation, preservation and / interoperability.» There is an initiative in Spain to standardise the description of metadata in sets of geo-spatial data: the Núcleo Español de Metadatos (Spanish Metadata Nucleus), which contains elements for the description of the particular characteristics of geographical data, includes all the obligatory registers from the ISO Norm 19115 and from the metadata study Dublin Core, traditionally used in library management. Being aware of the need of metadata, to optimise the search and retrieval of data, the objective is to formalise the documentation of archaeological data from the Núcleo Español de Metadatos (Spanish Metadata Nucleus), thus obtaining the interoperability of the archaeological information.

PROV-O: The PROV Ontology Tutorial

Provenance is key for describing the evolution of a resource, the entity responsible for its changes and how these changes affect its final state. A proper description of the provenance of a resource shows who has its attribution and can help resolving whether it can be trusted or not. This tutorial will provide an overview of the W3C PROV data model and its serialization as an OWL ontology. The tutorial will incrementally explain the features of the PROV data model, from the core starting terms to the most complex concepts. Finally, the tutorial will show the relation between PROV-O and the Dublin Core Metadata terms.

Reducing task’s redundancy – the strategy of Faculty of Pharmacy Library to centralize all scientific research

Introduction – Based on a previous project of University of Lisbon (UL) – a Bibliometric Benchmarking Analysis of University of Lisbon, for the period of 2000-2009 – a database was created to support research information (ULSR). However this system was not integrated with other existing systems at University, as the UL Libraries Integrated System (SIBUL) and the Repository of University of Lisbon (Repositório.UL). Since libraries were called to be part of the process, the Faculty of Pharmacy Library’ team felt that it was very important to get all systems connected or, at least, to use that data in the library systems. Objectives – The main goals were to centralize all the scientific research produced at Faculty of Pharmacy, made it available to the entire Faculty, involve researchers and library team, capitalize and reinforce team work with the integration of several distinct projects and reducing tasks’ redundancy. Methods – Our basis was the imported data collection from the ISI Web of Science (WoS), for the period of 2000-2009, into ULSR. All the researchers and indexed publications at WoS, were identified. A first validation to identify all the researchers and their affiliation (university, faculty, department and unit) was done. The final validation was done by each researcher. In a second round, concerning the same period, all Pharmacy Faculty researchers identified their published scientific work in other databases/resources (NOT WoS). To our strategy, it was important to get all the references and essential/critical to relate them with the correspondent digital objects. To each researcher previously identified, was requested to register all their references of the ‘NOT WoS’ published works, at ULSR. At the same time, they should submit all PDF files (for both WoS and NOT WoS works) in a personal area of the Web server. This effort enabled us to do a more reliable validation and prepare the data and metadata to be imported to Repository and to Library Catalogue. Results – 558 documents related with 122 researchers, were added into ULSR. 1378 bibliographic records (WoS + NOT WoS) were converted into UNIMARC and Dublin Core formats. All records were integrated in the catalogue and repository. Conclusions – Although different strategies could be adopted, according to each library team, we intend to share this experience and give some tips of what could be done and how Faculty of Pharmacy created and implemented her strategy.

Ssr-based Genetic Diversity And Structure Of Garlic Accessions From Brazil.

Garlic is a spice and a medicinal plant; hence, there is an increasing interest in 'developing' new varieties with different culinary properties or with high content of nutraceutical compounds. Phenotypic traits and dominant molecular markers are predominantly used to evaluate the genetic diversity of garlic clones. However, 24 SSR markers (codominant) specific for garlic are available in the literature, fostering germplasm researches. In this study, we genotyped 130 garlic accessions from Brazil and abroad using 17 polymorphic SSR markers to assess the genetic diversity and structure. This is the first attempt to evaluate a large set of accessions maintained by Brazilian institutions. A high level of redundancy was detected in the collection (50 % of the accessions represented eight haplotypes). However, non-redundant accessions presented high genetic diversity. We detected on average five alleles per locus, Shannon index of 1.2, HO of 0.5, and HE of 0.6. A core collection was set with 17 accessions, covering 100 % of the alleles with minimum redundancy. Overall FST and D values indicate a strong genetic structure within accessions. Two major groups identified by both model-based (Bayesian approach) and hierarchical clustering (UPGMA dendrogram) techniques were coherent with the classification of accessions according to maturity time (growth cycle): early-late and midseason accessions. Assessing genetic diversity and structure of garlic collections is the first step towards an efficient management and conservation of accessions in genebanks, as well as to advance future genetic studies and improvement of garlic worldwide.

Patterns of resistance to angular leaf spot, anthracnose and common bacterial blight in common bean germplasm

Diseases and insect pests are major causes of low yields of common bean (Phaseolus vulgaris L.) in Latin America and Africa. Anthracnose, angular leaf spot and common bacterial blight are widespread foliar diseases of common bean that also infect pods and seeds. One thousand and eighty-two accessions from a common bean core collection from the primary centres of origin were investigated for reaction to these three diseases. Angular leaf spot and common bacterial blight were evaluated in the field at Santander de Quilichao, Colombia, and anthracnose was evaluated in a screenhouse in Popayan, Colombia. By using the 15-group level from a hierarchical clustering procedure, it was found that 7 groups were formed with mainly Andean common bean accessions (Andean gene pool), 7 groups with mainly Middle American accessions (Middle American gene pool), while 1 group contained mixed accessions. Consistent with the theory of co-evolution, it was generally observed that accessions from the Andean gene pool were resistant to Middle American pathogen isolates causing anthracnoxe, while the Middle American accessions were resistant to pathogen isolates from the Andes. Different combinations of resistance patterns were found, and breeders can use this information to select a specific group of accessions on the basis of their need.

Genetic variability in cultivated common bean beyond the two major gene pools

It is generally accepted that two major gene pools exist in cultivated common bean (Phaseolus vulgaris L.), a Middle American and an Andean one. Some evidence, based on unique phaseolin morphotypes and AFLP analysis, suggests that at least one more gene pool exists in cultivated common bean. To investigate this hypothesis, 1072 accessions from a common bean core collection from the primary centres of origin, held at CIAT, were investigated. Various agronomic and morphological attributes (14 categorical and 11 quantitative) were measured. Multivariate analyses, consisting of homogeneity analysis and clustering for categorical data, clustering and ordination techniques for quantitative data and nonlinear principal component analysis for mixed data, were undertaken. The results of most analyses supported the existence of the two major gene pools. However, the analysis of categorical data of protein types showed an additional minor gene pool. The minor gene pool is designated North Andean and includes phaseolin types CH, S and T; lectin types 312, Pr, B and K; and mostly A5, A6 and A4 types alpha-amylase inhibitor. Analysis of the combined categorical data of protein types and some plant categorical data also suggested that some other germplasm with C type phaseolin are distinguished from the major gene pools.

RECERCAT. El Dipòsit de la Recerca de Catalunya

Seguint la tendència mundial de crear dipòsits institucionals d'accés lliure per recopilar i preservar els documents d'investigació generats en les institucions acadèmiques, el CESCA i el CBUC han posat en funcionament RECERCAT. RECERCAT és un dipòsit cooperatiu de documents digitals que inclou la literatura de recerca de les universitats i dels centres d'investigació de Catalunya, com ara articles encara no publicats (preprints), comunicacions a congressos, informes de recerca, working papers, projectes de final de carrera, memòries tècniques, etc. La comunicació pretén explicar els processos que s'han seguit per posar en marxa aquest projecte: des de la selecció i adaptació del programari amb el que funciona (DSpace), fins als treballs duts a terme per establir les polítiques d'accés, d’introducció de dades, de metadades Dublin Core necessàries per descriure els documents, el tipus de llicència de les Creative Commons sota la qual es troben subjectes els documents, etc.

How collaboration could contribute to make Catalan journals visible on the Internet?

Cooperation between libraries is a universal language spoken in different dialects. In 1996 the libraries of the state-funded universities and the National Library of Catalonia (Spain) formed the Consortium of Academic Libraries of Catalonia (CBUC) to act as a channel for cooperation. The organization and activities of CBUC are an example of how this universal language has been adapted to the specific characteristics of the Libraries of Catalonia. Catalonia is an autonomous region of Spain with 7 million inhabitants with its own language, history and traditions and with a strong feeling of own identity that facilitates the cooperation. Thanks to this (and also to the hard work of the member libraries), since then, CBUC has created a union catalogue, an interlibrary lending program, the Digital Library of Catalonia, a cooperative store, different cooperatives repositories and other cooperation programs. One of these cooperatives repositories is RACO (Catalan Journals in Open Access, www.raco.cat) where can be consulted, in open access, the full-text articles of scientific, cultural and scholar Catalan journals. The main purpose of RACO is to increase the visibility and searches of the journals included and to spread the scientific and academic production published in Catalonia. This purpose makes specific in three aims: encourage the electronic edition of Catalan journals; be the interface that allows the whole search of all the journals and provide the instruments for its preservation. There are currently 244 journals in RACO, that includes more than 85.000 articles (80% in OA) from 50 publishing institutions. Since it got into operation it has had more than 4 millions of queries. These 244 journals offer the full-text of all the published issues. Nevertheless, some journal can have a delay between the introduction of the table of contents and the full-text for the recent issues. From 2005 we have a plan of retrospective digitization that has allowed to digitize more than 350.000 pages of back issues. The RACO repository works with the open source program OJS (Open Journal Systems, http://pkp.sfu.ca/ojs/) and uses Dublin Core Metadata and the interoperability protocol created by Open Archives Initiative (OAI) which allows to increase the visibility of the articles published in journals offering oneself together with other international repositories.

Interoperability issues between learning object repositories and metadata harvesters

In this paper we describe an open learning object repository on Statistics based on DSpace which contains true learning objects, that is, exercises, equations, data sets, etc. This repository is part of a large project intended to promote the use of learning object repositories as part of the learning process in virtual learning environments. This involves the creation of a new user interface that provides users with additional services such as resource rating, commenting and so. Both aspects make traditional metadata schemes such as Dublin Core to be inadequate, as there are resources with no title or author, for instance, as those fields are not used by learners to browse and search for learning resources in the repository. Therefore, exporting OAI-PMH compliant records using OAI-DC is not possible, thus limiting the visibility of the learning objects in the repository outside the institution. We propose an architecture based on ontologies and the use of extended metadata records for both storing and refactoring such descriptions.

Andalusian Health Repository: Promoting the scientific health output among professionals and providing citizens with quality health information

The Andalusian Public Health System (Sistema Sanitario Público de Andalucía -SSPA) Repository is the open environment where all the scientific output generated by the SSPA professionals, resulting from their medical care, research and administrative activities, is comprehensively collected and managed. This repository possesses special features which determined its development: the SSPA organization and its purpose as a health institution, the specific sets of documents that it generates and the stakeholders involved in it. The repository uses DSpace 1.6.2, to which several changes were implemented in order to achieve the SSPA initial goals and requirements. The main changes were: the addition of specific qualifiers to the Metadata Dublin Core scheme, the modification of the submission form, the integration of the MeSH Thesaurus as controlled vocabulary and the optimization of the advanced search tool. Another key point during the setting up of the repository was the initial batch ingest of the documents.

Genome-Wide Prediction Methods in Highly Diverse and Heterozygous Species: Proof-of-Concept through Simulation in Grapevine.

Nowadays, genome-wide association studies (GWAS) and genomic selection (GS) methods which use genome-wide marker data for phenotype prediction are of much potential interest in plant breeding. However, to our knowledge, no studies have been performed yet on the predictive ability of these methods for structured traits when using training populations with high levels of genetic diversity. Such an example of a highly heterozygous, perennial species is grapevine. The present study compares the accuracy of models based on GWAS or GS alone, or in combination, for predicting simple or complex traits, linked or not with population structure. In order to explore the relevance of these methods in this context, we performed simulations using approx 90,000 SNPs on a population of 3,000 individuals structured into three groups and corresponding to published diversity grapevine data. To estimate the parameters of the prediction models, we defined four training populations of 1,000 individuals, corresponding to these three groups and a core collection. Finally, to estimate the accuracy of the models, we also simulated four breeding populations of 200 individuals. Although prediction accuracy was low when breeding populations were too distant from the training populations, high accuracy levels were obtained using the sole core-collection as training population. The highest prediction accuracy was obtained (up to 0.9) using the combined GWAS-GS model. We thus recommend using the combined prediction model and a core-collection as training population for grapevine breeding or for other important economic crops with the same characteristics.
