List.MID: A MIDI-Based Benchmark for Evaluating RDF Lists

“…These models were surveyed by selecting them from the following sources, including W3C standards 7 ontology design patterns [10], resource track papers in ISWC (e.g. [3], [18]), and lookups of relevant terms in Linked Open Vocabularies [28]. For a further detail and a description of the surveying methodology, see [8].…”

“…URI-based Lists A more practical approach followed by many RDF datasets [3,18] consists of establishing list membership through an explicit property or class membership, and assigning order by a unique identifier embedded in the element's URI. For instance, the triple <http://ld.zdb-services.de/resource/ 1480923-0> a <http://purl.org/ontology/bibo/Periodical> indicates that the subject belongs to a list of periodicals with list order 14809234; the triple <http://purl.org/midi-ld/piece/8cf9897/track00> midi:hasEvent <http: //purl.org/midi-ld/piece/8cf9897/track00/event0006> identifies the 7th event in a MIDI track [18] (see Figure 3).…”

“…With this variety of alternatives, many questions arise on practical and performance issues with respect to RDF lists. For example, it is hard to choose one such implementation in large-scale, list-based RDF datasets [18] without knowing the impact of such choice in query performance. Differently, other users may be interested in favoring list readability over performance.…”

“…In this paper, we introduce the List.MID benchmark, an RDF list data generator and query template set specifically designed for the evaluation of RDF lists. The benchmark has two focus points: (a) to cover as many RDF list implementations as possible, following a systematic study that surveys and summarizes different RDF list modeling practices into 6 different RDF list modeling templates [8]; and (b) to create such multi-model RDF lists out of real-world data, through the large-scale, list-rich symbolic music notation dataset of the MIDI Linked Data cloud [18]. Specifically, the contributions of the paper are:…”

“…-We list and describe 6 abstract RDF list modeling patterns recently surveyed [8] (Section 3.1) -We describe the List.MID data generator (Section 3.2), which generates RDF list data according to these patterns from the MIDI Linked Data cloud dataset [18]; and a set of SPARQL query templates for retrieval (Section 3.3) -We show evidence of use and potential adoption for our proposed benchmark (Section 4)…”
