The growing diffusion of perspectivism within the debate on information system ontologies [ISOs] does not correspond to a thorough analysis of what perspectivism specifically consists of. This paper aims to fill this void. First, I show what supporting perspectivism in information system ontologies [PISO] means in terms of (minimal) claims and implications; then I argue that the definitions of ISO implicitly assume PISO’s (minimal) claims or, in other words, that ISOs presuppose and maintain PISO. Section 2 presents the main definitions of ISO. Section 3 specifies what claims are common to all perspectivists in ISO. Sects. 4–7 analyze the implications of those claims. Section 8 explores the chance of multiple perspectivisms within ISOs’ domain. Finally, Sects. 9–10 assume that, if PISO’s (minimal) claims and (their) implications can be inferred from ISO’s definitions, then ISOs are perspectivist, or PISO’s minimal claims are assumptions underlying ISOs.

视角主义在信息系统本体论[ISO]争论中的日益扩散并不对应于对视角主义具体内容的彻底分析。本文旨在填补这一空白。首先，我将展示支持信息系统本体 [PISO] 中的视角主义在（最小）主张和含义方面意味着什么；那么我认为 ISO 的定义隐含地假定了 PISO 的（最低限度）主张，或者换句话说，ISO 预设并维护了 PISO。第 2 节介绍了 ISO 的主要定义。第 3 节详细说明了 ISO 中所有观点主义者共同的主张。教派。 4-7 分析了这些主张的含义。第 8 节探讨了 ISO 领域内多种视角的可能性。最后，教派。 9-10 假设，如果 PISO 的（最低）声明及其（其）含义可以从 ISO 的定义中推断出来，则 ISO 是透视主义者，或者 PISO 的最低声明是 ISO 的假设。
