Metadata consists of elements that describe specific content of data. When structured according to standards, they contribute to data interoperability. This study presents a secondary study, a Systematic Mapping (SM), to search for metadata patterns that can be used in the field of Computer Science (CS), especially in the subjects of Software Engineering (SE) and Information Systems (IS). At the end of the search string execution, 43 studies were analyzed. Of these, 23 studies were selected. Based on the observed results, a promising research area is identified, focusing on the adoption of metadata standards in various activities within the context of CS, SE, and IS.

“…For the aloha-based scheme, the authors in [26] designed a tag anti-collision scheme to minimize the total time slots required to identify tags within the query region of RFID readers. By using the secant iterative method, Gao et al in [27] proposed an aloha-based anti-collision scheme, which could effectively estimate the number of tags. Moreover, by taking Bayesian inference into account, the cross-layer tag anti-collision scheme was investigated in [28,29], which could achieve optimal identification efficiency.…”

“…First, the proposed RFID-integrated UAVaided networks in [11][12][13][14][15][16][17][18][19][20][21][22][23] consider the flexibility of UAVs but ignore the characteristics of the dense RFID environment, such as the adaptive power control for the reader. Moreover, the designed tag anti-collision schemes in [27][28][29][30][31][32] are usually based on the conventional single frequency tags, which leave multifrequency tags out of consideration.…”

In this paper, we investigate tags in anti-collision applications of radio frequency identification (RFID) technology in unmanned aerial vehicle (UAV)-aided vehicular ad hoc networks (VANETs). The integration of RFID technology in UAV-aided VANETs can provide reliable traffic-related services for vehicles. However, multiple tags’ simultaneous responses to a reader mounted on a UAV, denoted as tag collision, gravely affect the correct tag detection on each vehicle. Therefore, in order to decrease the collision probability and improve the throughput, we propose a multi-frequency tag identification method. In the proposed scheme, we devise a tag grouping method based on adaptive power control to make the reader dynamically match the optimal frame length. Based on the above matching results, we introduce a tag estimation method using the optimal weight to improve the accuracy of tag estimation. We theoretically analyze the closed-form expression of the security outage probability expression. Finally, our simulation results demonstrate that the proposed tag anti-collision scheme achieved significant performance superiority in terms of the throughput and identification time slots.

Internet of Things (IoT) and cloud metadata have highly sensitive details and facts about data and objects; it usually holds confidential information about the data for which there are access restrictions. Hence, it forms the most abundant source of information about any digital object from which the actual data can be rebuilt or duplicated with the same level of originality. However, it appears to be an emerging threat vector in IoT and cloud environments. If a misfeasor acquires access to the metadata information, then there arises a security threat. This article proposes a novel method on a bifold layered blockchain network, referred to as MetaInfoChain, to enhance the integrity and access controllability of safe storage. By default, blockchain protects the data while a permissioned blockchain forms an access control layer over the core blockchain. The acquired instance, compute, and the unique credentials sign device metadata to enforce controllability and validated by minters and add it to the base layer of the MetaInfoChain. Subsequently, we propose a consensus attainment algorithm to build an unrefined block on a candidate block comprising metadata packages. Consequently, all the nodes receive an unrefined block replica, which can afford absolute integrity. The top layer of MetaInfoChain is sensible to generate tamper-resistant metadata by executing hybrid PoS-PoW tasks on the unrefined block, causing robust integrity. After accomplishing all the checks, it endorses the MetaInfoChain to append the block with 35% block time efficiency in the base layer with a 56% throughput hike.
