Open Source Software for Digital Preservation Repositories: a Survey <s> Preservation Standards / Metadata Standards Support <s> Encoded Archival Description (EAD) is an emerging standard used internationally in an increasing number of archives and manuscripts libraries to encode data describing corporate records and personal papers. The individual descriptions are variously called finding aids, guides, handlists, or catalogues. While archival description shares many objectives with bibliographic description, it differs from it in several essential ways. From its inception, EAD was based on Standard Generalized Markup Language (SGML), and, with the release of EAD version 1.0 in 1998, it is also compliant with EXtensible Markup Language (XML). EAD was and continues to be developed by the archival community. While development was initiated in the United States, international interest and contribution are increasing. EAD is currently administered and maintained jointly by the Society of American Archivists and the United States Library of Congress. Developers are currently exploring ways to internationalize the administration and maintenance of EAD to reflect and represent the expanding base of users. ::: ESARBICA Journal Vol.20 2001: 71-80 <s> BIB001 </s> Open Source Software for Digital Preservation Repositories: a Survey <s> Preservation Standards / Metadata Standards Support <s> Abstract An increasing number of libraries that receive materials using Internet document delivery (IDD) systems are creating electronic document delivery services to redirect those materials directly to their customers. While academic libraries have embraced IDD and electronic document delivery systems, hospital libraries have faced significant barriers which often prevent them from implementing such services. The docMD project has been created to investigate the use of a centralized document mediation center as a method of overcoming these barriers. During the eighteen-month project timeline a centralized center will be established that will receive documents intended for project libraries and that are sent using an Ariel compatible IDD system. The documents will be converted to the Portable Document Format (PDF) and delivered directly to their requestors using the Web. docMD is a project of the John A. Prior Health Sciences Library at the Ohio State University with assistance from the Cleveland Library... <s> BIB002 </s> Open Source Software for Digital Preservation Repositories: a Survey <s> Preservation Standards / Metadata Standards Support <s> Motivated by preservation and resource discovery, we examine how digital resources, and not just metadata about resources, can be harvested using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). We review and critique existing techniques for identifying and gathering digital resources using metadata harvested through the OAI-PMH. We introduce an alternative solution that builds on the introduction of complex object formats that provide a more accurate way to describe digital resources. We argue that the use of complex object formats as OAI-PMH metadata formats results in a reliable and attractive approach for incremental harvesting of resources using the OAI-PMH. <s> BIB003
This section identifies the preservation and metadata standards supported by each software. The preservation standards are OAIS  , OAI-PMH BIB003 (versions 1 and 2) and SRU  . The identified metadata standards are Dublin Core  , MARC / MARC21 / MARCXML   , EAD BIB001 , PREMIS  , METS  , MODS  , DIDL  , MIX  , AES  , DocMD BIB002 and TextMD  . Table 3 shows the support for these standards given by each software. Specifically, in Table 3 , a check sign means that the standard is supported. The inexistence of a check sign means that no indication of the standard's support was found during this study. Nonetheless, we cannot assert that any of the standards are unsupported, as many of the systems studied have flexible architectures, therefore supporting 3 rd parties' plugins, capable of enabling those standards support.Note that Xena does not support any of the covered standards. Additionally, since only DAITSS natively supports the MIX, AES, TextMD, DocMD, audio and video formats, these standards are not included in Table 3to preserve space. For the same reason, the column MARC includes the standards MARC, MARC21 and MARCXML. Table 3 . Standards and protocols supported by each of the surveyed software solutions. Table 4 .
