A partire dal marzo 2023, il nodo italiano dell’infrastruttura di ricerca OPERAS (CNR-ILIESI) ha curato lo studio di fattibilità, la specifica tecnica e il modello di orchestrazione dei servizi per il Marketplace del progetto H2IOSC – Humanities and Heritage Italian Open Science Cloud. Il Marketplace A progettato per consentire di integrare risorse eterogenee provenienti dalle infrastrutture di ricerca federate (OPERAS, E- RIHS, CLARIN, DARIAH), favorendo da un lato la cooperazione e la condivisione tra ecosistemi digitali, dall’altro la collaborazione e il coinvolgimento attivo degli utenti. Il contributo descrive la soluzione API-driven della piattaforma, con un’architettura a tre livelli dove i workflow applicativi e descrittivi diventano elementi qualificanti del modello. In particolare, viene formalizzata la distinzione tra orchestrazione (in cui il Marketplace coordina servizi eseguiti remotamente su sistemi esterni) e composizione (in cui i servizi operano localmente all’interno di una singola piattaforma). I workflow applicativi e descrittivi diventano elementi qualificanti del modello, rappresentando non solo strumenti tecnici, ma servizi capaci di estendere le funzionalità del Marketplace e di abilitare scenari avanzati di elaborazione e integrazione dei dati e funzionalità collaborative preservando la responsabilità dei fornitori e la sostenibilità del sistema. Viene descritto il ruolo dei protocolli e dei flussi di harvesting basati su OAI-PMH, la visualizzazione delle risorse, le modalità di ricerca, la creazione e l’esecuzione di workflow applicativi tramite WSO2 Micro Integrator, e gli strumenti di analisi di utilizzo. Il Marketplace risponde così alle necessità di progetto e ai bisogni degli utenti, configurandosi come infrastruttura socio-tecnica capace di sostenere pratiche di ricerca e non come semplice repertorio descrittivo.

Abstract
Since March 2023, the Italian node of the OPERAS research infrastructure (CNR-ILIESI) has been responsible for the feasibility study, technical specification, and service orchestration model for the H2IOSC – Humanities and Heritage Italian Open Science Cloud – Marketplace project. The Marketplace is designed to integrate heterogeneous resources from federated research infrastructures (OPERAS, E- RIHS, CLARIN, DARIAH), fostering cooperation and sharing between digital ecosystems on the one hand, and collaboration and active user engagement on the other. The paper describes the platform’s API-driven solution, with a three-tier architecture where application and descriptive workflows become key elements of the model. Specifically, the distinction between orchestration (in which the Marketplace coordinates services executed remotely on external systems) and composition (in which services operate locally within a single platform) is formalized. Application and descriptive workflows become key elements of the model, representing not only technical tools but also services capable of extending the Marketplace’s functionality and enabling advanced data processing and integration scenarios and collaborative features while preserving supplier accountability and system sustainability. The role of OAI-PMH-based harvesting protocols and flows, resource visualization, search methods, the creation and execution of application workflows using WSO2 Micro Integrator, and usage analysis tools are described. The Marketplace thus responds to project and user needs, becoming a socio-technical infrastructure capable of supporting research practices rather than a simple descriptive repository.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
