O objetivo do projeto «Polona para Bibliotecas 2.0» (a seguir designado por Projeto) consiste no desenvolvimento do serviço eletrónico Polona para bibliotecas (a seguir designado por serviço eletrónico do AO), melhorando a qualidade e a maturidade com base no potencial do serviço eletrónico digital, o que melhorará significativamente o acesso dos utilizadores individuais e institucionais aos recursos recolhidos em bibliotecas em todo o país. O E-service PDB é uma interface que apresenta os recursos acumulados no Repositório Digital da BN (doravante RCBN), que atualmente contém mais de 3 milhões de publicações. No âmbito do projeto, o sistema Polona será modernizado para permitir aos utilizadores: 1) placing an order for digitisation 2) placing an order for file sharing in various formats 3) sharing the results of own research by creating public notes 4) creating public collections and functionalities of creating social websites (at individual user level), on which there will be collections and public notes 5) creating “light” (small-size) public collections and making it easier for users to contact them with scans of the works provided at the user’s request, which will increase the openness and availability of the collections, as well as the ease of viewing of the data of the Internet and the review of the Internet data by means of scanned works at the user’s request, which will increase the openness and availability of the collections, as well as the ease of reviewing of the data of the Internet, and the ease of review of the Internet access data by means of scans of the works made available at the user’s request, which will increase the openness and availability of the collections, as well as the ease of review of the Internet data, and the ease of reviewing the availability of data in various formats (3) sharing the results of own research by creating public notes to digital objects 4) creating public collections and functionalities of creating social websites (at the individual user level), on which there will be a public collections and notes 5) creating “lightless” (little-size) data errors (little size) of pdf files with scans of the works made available at the user’s request, which will increase the availability and accessibility of the collections of the users, as well as the ease of reviewing of the Internet data and the ease of reviewing of the Internet access data (small size) with scanned works on the user’s request, which will increase the openness and availability of the collections, as well as the ease of reviewing of the data of the user and the ease of reviewing the access of the Internet objects and the accessibility of the data of the users on request, which will increase the openness and availability of personal data, as well as the ease of reviewing of data of the Internet, and the ease of reviewing of the data of the Internet (small size) with the scanned works made available at the user’s request, which will increase the openness and availability of personal data, as well as the ease of viewing the Internet data and the review of the Internet data by means of the user’s access files on the user’s request, which will increase open These changes can be achieved through the modernisation of the RCBN in terms of: 1) extensão de ferramentas OCR (reconhecimento óptico de caracteres) 2) desenvolvimento e implementação de uma nova arquitetura RCBN baseada em microsserviços, comunicação moderna entre vários componentes do sistema 3) extensão da API RCBN (Application Programming Interface).
