Concretely, how should we know whether 5 is related to Greek or English, when rebuilding the first row of the CSV source.

Tennison and Kellogg defines a CSV in such a way that, for each row, the associated cells are implicitly kept together by including them in the same line. In this case, 1 would measure a similarity equal to 1. To exemplify the main idea, let us consider the RDF dataset and the set of rules of Fig.

Overall, none of these solutions considered the reverse mapping, namely from the generated RDF dataset to the original tabular data source. Dataset into values of the column datasetID. AnnoCultor comes with built-in tagging with Geonames and a custom time ontology. Copyright Carlo Allocca, Alexandros Gougousis. W3C Working Draft 08 January ; converdor Before transforming them into RDF datasets conversoe applied a pre-preprocessing to make sure that their content would not generate any of the issues analyzed in the Study Area Description section and further analyzed in the Discussion section.

In contrast, RML2CSV is built on top of RML that provides a mapping language for expressing customized mappings from a heterogeneous data source to an RDF data model that does not necessary reflect the original structure as showed above. Conversoor, we use the set rjl RML rules to reconstruct all the rows from line 5 to line 9 using the ReverseRow sub-call as reported in the Appendix. This would mean to change the workflow of the entire forward process of RML.

For such cases, the reuse of preserved RDF datasets would require a heavy ad-hoc pre-processing for understanding Flouris and Meghiniextracting and arranging Stefanova and Risch a the data that satisfy the user intended use, including the transformation of the RDF data back to their original format Stefanova and Risch b. Based on such observation, we asked how we can make sure that we deal with types of scenario exemplified in Fig.

In this paper we argue that an important aspect of long-term preservation of digital objects, such RDF datasets, is to provide full support for reusing such data, including mechanisms to bring back the data to their original format.

Before formalizing it, we explain it by continuing the reverse of the RDF dataset of Fig. Does it solve the problem that is supposed to? Combining 12 and 3 together we have that: RML2CSV rebuilds the content with the data structure as the original one, offering more advanced digital preservation services in supporting long-term access.

The paper continues as in the following: In what follow we present and discuss two of them: To face with the. To this end, we based such a comparison on computing a similarity measure between csv r and csv oas expressed in the following: Thus, in this paper we make a specific assumption on the graph structure underlying the mapping rules.

Furthermore, as our solution is based on [R2]RML mapping language, it provides the additional advantage that we can perform both transactions, CSV data source to RDF dataset and vice-versa, within the same framework, that none of the discussed work does.

Technical specification Programming language: Related Work To the best of our knowledge, there is no other study investigating the reversing of an RDF dataset for reconstructing the original tabular data source of CSV type. When we come to the issue of long-term preservation of such RDF-based digital objects, it is important to provide full support for reusing them in the future.
