Object Sharing in Mbya Guarani: A Case of Asymmetrical Verbal Serialization?

In this paper, we intend to describe and discuss the grammatical status of the V1-V2 (Cy/vy) constructions found in Mbya Guarani which can express simultaneous events, among other meanings, and which involve a single clause. We suggest here that this verbal complex can be treated as a case of asymmetrical verbal serialization because it contains verbs from a major lexical class, occupying the V1 slot, followed by a more restricted intransitive verbal class, such as movement, postural, or stative verbs, which stands in the V2 position. The curious property of these constructions is that V2 can be transitivized through the attachment of applicative or causative morphemes and “share” its object with transitive V1. “Object sharing” is another property attributed to serialization, as suggested by Baker and Baker and Stewart, which may be seen as a strong argument in favor of the present hypothesis. We will also provide evidence to distinguish Mbya Guarani V1-V2 (Cy/vy) complex from other constructions, such as temporal and purpose subordinate clauses, involving the particle vy.

A Class Focused Approach to Research Outputs and Policy Literature Metadata

Successful research object sharing requires that systems and users understand the structure, semantics and rules that govern a given research object collection. A number of metadata standards define ontologies and vocabularies for consistent expression of research object semantics. Supporting, clarifying and sometimes extending these standards are metadata application profiles (MAPs). MAPs play a key role defining metadata element cardinality and data types. MAPs may also mandate or recommend controlled vocabularies, where metadata standards have not already mentioned these in formal range declarations, encoding schemes and semantics that are to be consumed by external systems. MAPs also guide design options for in-house systems and workflows. In this paper, development of a draft MAP for grey-literature policy and research collections is discussed. A focus of the discussion is the considerations around selection and adoption of metadata standards given the research data and literature communities in the APO stakeholder map. This paper presents a work-in-progress version of a Dublin Core Application Profile (DCAP) candidate. The Analysis & Policy Observatory Metadata Application Profile (APO-MAP) takes research object class structure as a starting point and considers class model options, especially given the availability of registry services and Persistent Indenter (PID) systems. The discussion finds that MAP development progresses towards a best fit that balances the need to adopt widely supported standards, local business drivers, and community acceptance.

Towards Building Reuse-Based Digital Libraries for National Universities in Patagonia

This article presents a case study exploring the use of software product lines and reference models as mechanisms of a reuse-based design process to build digital libraries. As a key component in a modern digital library, the reference architecture is responsible for helping define quality of the resulting repository. It is true that many efforts have been addressed towards providing interoperability; however, repositories are expected to provide high levels of reuse too, which goes beyond that of simple object sharing. This work presents the main steps we followed towards building a reusable digital library capable of accommodating such needs by (i) providing mechanisms to reuse resources, and (ii) enabling explicit sharing of commonalities in a distributed environment.
