The aim of this study was to investigate the views of administrators and librarians of Allameh Tabataba'i University libraries on digital preservation in the cloud environment.The present study is applied in nature and with a descriptive-survey method in two stages. In the first stage, by reviewing the texts of a researcher-made questionnaire with five components: " This questionnaire was designed on a five-point Likert scale and its reliability was 0.852 using Cronbach's alpha. In the second stage, the collected data were analyzed based on descriptive statistics (mean, median, standard deviation and variance) and one-sample t-test. Friedman test was also used to rank the factor of "possible challenges and barriers".Findings showed that the majority of participants were moderately familiar with the concepts of digital protection in the cloud environment. Also, from the point of view of managers and librarians of Allameh Tabataba'i University libraries, "the state of data trust and security in cloud protection" and "the availability of technological infrastructure for cloud protection in the university" is at a desirable level (p <0.05). "The organizational situation of the university for protection in the cloud environment" is at a moderate and relatively desirable level and "Knowledge and awareness required in cloud protection in librarians" is at a relatively undesirable level (p-value >0.05).

IntroductionOrganizational ontologies are a type of ontology that focuses on identifying and documenting organizational entities. These tools provide a common conceptualization of organizational entities and are utilized for representing organizational knowledge, describing organizational structures, identifying entities, and revealing the features and relationships of entities. They also, support the dissemination of organizational data, generated reports, organizational history, human resources, and the roles of each of these through a linked data approach. Therefore, the purpose of this research was to design the business ontology of Ehya Sepahan Company based on semantic web data models.Research Question(s)In the present research, the following questions have been addressed:- What are the internal and external entities of the Ehya Sepahan Company and their attributes?- To what extent do the entities and attributes of the Ehya Sepahan Company align with the Schema.org data model?- How is the organizational ontology of the Ehya Sepahan Company structured based on the organizational ontology of the World Wide Web Consortium?Literature ReviewResearch related to ontology design can be divided into two main categories:2.1. Studies that examine the application of ontologiesThe first category includes studies that examine the application of ontologies or the design of ontologies in specific contexts. Research by Sharif (2008), Bavakhani (2015), Hassanzadeh, Kahani, and Pourmasoumi (2016), Mardpour and Dehghan-Tafti (2017), Akbari and Rajabi-Bahjat (2018), Fuchs-Kittowski and Faust (2008), Cavaliere et al. (2019), and Outa et al. (2020) fall into this category. In this context, Bavakhani (2015) explored the interrelationship between ontologies and knowledge management. Cavalier et al. (2019) designed an ontology design model for analyzing video content captured by drones in their study. The findings of the studies in this group indicate that in contemporary organizations, there is a necessity to utilize ontologies in processes related to existing knowledge. 2.2. Studies that specifically address the design of organizational ontologiesThe second category includes studies that specifically address the design of organizational ontologies for various organizations. Research by Delavari (2018), Rajabi and Alineghizadeh Ardestani (2019), Gualtieri and Rafolu (2005), Santos et al. (2013), and Elnagar et al. (2022) are included in this group. Rajabi and Alineghizadeh Ardestani (2019) presented a data-driven approach to develop an architectural model using organizational ontology. Elnagar et al. (2022) offered a framework for the automatic production of ontologies from an organizational perspective in their research.MethodologyThis study was developmental-applied research in nature and qualitative research in terms of approach, conducted using qualitative content analysis and design methods. The statistical population includes all entities of the Ehya Sepahan Company (data entities, human resources, organizational positions), as well as the classes and attributes present in the organizational ontology.The research was conducted in several sections; initially, by examining the organizational ontology, the classes and attributes needed for modeling the entities and attributes present in the Ehya Sepahan Company were identified. Subsequently, through reviewing organizational documents, the organizational structure, job descriptions, and various departments of the company, the organizational entities and the characteristics of each were identified. With the identification of the entities and main concepts of the company, the necessary classes and attributes were determined. Since the aim of this study was to design a company ontology based on a semantic web data model, alongside the main classes and attributes of its organizational ontology, standard metadata classes and attributes from the Schema.org data model were used. In this research, Observation and documentary methods and a checklist are utilized for gathering the required data.ResultsThe findings of this research revealed that the entities of Ehya Sepahan Company are divided into internal and external entities. In total, 9 main entities and 3 external entities were identified for the company’s ontology. Various attributes were provided for each of these 12 entities. A total of 152 attributes were identified for the 12 entities of the company, and these attributes were assigned to different entities. For the internal entities, 147 attributes were used, while for the external entities, 21 attributes were utilized.The findings revealed that most of the attributes considered for company entities are presented in the schema.org standard. So, all the mentioned attributes for Organization, Person, Website, and Product entities in schema.org are consistent with the attributes needed to describe the company entities. the investigation of organizational ontology showed that this ontology has 9 entities and all these entities were used to design the ontology of Ehya Sepahan company. Likewise, the results showed that there is a good alignment between the attributes of the organizational ontology and the schema.org metadata standard. DiscussionBased on the finding it could be said that the entities of the company each possess unique characteristics. Accordingly, specific attributes were considered in the organizational ontology based on the features of each of these entities to provide an accurate and appropriate description of the company and its entities. For a large number of attributes considered for the company’s entities, suitable attributes are provided in schema.org. All the attributes mentioned for organizational entities, such as person, website, and product, align with the necessary attributes needed to describe the company’s entities in schema.org. The reason for this suitable alignment between entities and the attributes of the organizational ontology and schema.org is the comprehensive perspective of schema.org as a semantic web data model for describing various types of data entities.ConclusionIn general, it can be stated that organizational ontologies are one of the efficient tools for accurate description and knowledge discovery of data entities of organizations that can be used to facilitate and speed up processes and decisions in the organization.

The purpose of the study is to orient the Digiqual model with the 5S theoretical framework in digital library concepts. The research type is practical and it was conducted using the analysis of qualitative content method. The validity of the research is a logical one which is based on personal subjective judgment. The reliability of the study is a type of credibility based on counseling the specialists in the field of digital libraries. In the digiqual model, content (information) and community (user) as two processes in digital libraries are related to technical environment and human/system interaction. Societies (actors) as a factor in dimensions of some ‘S’ concepts in digital libraries, including accessibility and pertinence of the digital object and also availability, effectiveness, extensibility, reusability and reliability of services, is appreciable with digiqual model. Scenario as a factor in dimensions of ‘S’ concepts in digital libraries including pertinence, and conservation of the digital object; availability, effectiveness, extensibility, reusability and reliability of services, is appreciable with digiqual model. Streams and structures as factors in dimensions of some ‘S’ concepts in digital libraries including accessibility, conservation, relevance, similarity, significance and timeliness of the digital objects; accuracy, completeness and conformance of metadata specification; completeness as a collection; completeness and consistency of the catalog; completeness and consistency in the repository; efficiency and effectiveness of services, is appreciable with digiqual model. Space as a factor doesn’t exist in any of the ‘S’ concept dimensions in digital libraries and it is not appreciable with digiqual model. Finally, the development of ‘S’ concepts in digiqual dimensions in order to integrate the quality of services is proposed.
