ABSTRACT

Introduction:

Digital preservation in Web archiving will only be possible with the effective use of metadata standards. These standards are the ones that determine the persistence, consistency, comprehensibility, the access, and representation of selected sites, collected and stored in Web archives, besides defining the archivability of sites and the interoperability among systems.

Objective:

In this context, the objective of the article was to identify and define which metadata standards could be judged by memory institutions and universities so that they could enable digital preservation in Web archives.

Methodology:

For this, a qualitative, exploratory, and descriptive research was done, using the bibliographic method from a non-systematic inventory together with a review and analysis of the literature content. The Dublin Core, MODS, EAD, VRA Core, PREMIS, and METS standards were selected and analyzed.

Results and Conclusion:

The analysis of the results indicates that Dublin Core, MODS, EAD, and VRA Core supported METS and PREMIS in detecting and documenting technical aspects of sites and proving their authenticity, context, and origin. METS can manage archived sites by acting as OAIS information packages, while Dublin Core proved to be an exponent for Web archiving through its use in remarkable area initiatives.

MODS (version 3.7)	- XML schema derived from MARC 21 seen as richer than DC and simpler than full MARC; Can be used together with MADS and as a METS extension scheme; and Applicable to digital library objects and to archived sites, such as those in the Library of Congress Web Archive collections.	▪ Title information (<titleInfo>) Name (<name>) Resource type (<typeOfResource>) Genre (<genre>) Origin Information (<originInfo>) Language (<language>) Physical Description (<physicalDescription>) Abstract (<abstract>) Table of Contents (<tableOfContents>) Note (<note>) Subject (<subject>)	▪ Related item (<relatedItem>) Identifier (<identifier>) Location (<location>) Access Condition (<accessCondition>) Part (<part>) Extension (<extension>) Record Information (<recordInfo>)
EAD3 (version 1.1.1)	- Thorough XML schema and DTD, which is compliant with ISAD(G) archival description standard; Can be used in conjunction with EAC-CPF and includes both indication of corresponding elements in MARC, MODS, ISAD(G) and HTML as mappings (crosswalks) for MARC 21, MODS and ISAD(G) ; and Applicable to the coding of archival search instruments, such as the California Online Archive Search Instruments that provide detailed descriptions of the collections from the University of California Irvine web archive in the United States.	▪ Unit title (<unittitle>) Origin (<origination>) Personal Name (<persname>) Organization Name (<corpname>) Family Name (<famname>) Controlled Access Headers (<controlaccess>) Abstract (<abstract>) Accruals (<accruals>) Acquistiotion Information (<acqinfo>) Biography or history (<bioghist>) Scope and Contents (<scopecontent>) Custodian History (<custodhist>) Descriptive Identification Note (<didnote> Other Descriptive Data (<odd>) Unit Date (<unitdate>)	▪ Genre/Physical Characteristic (<genreform>) Physical Description (<physdesc>) Digital Archive Object (<dao>) Unit Identification (<unitid>) Material Language (<langmaterial>) Language (<language>) Physical Structure (<physdescstructured>) Related Material (<relatedmaterial>) Access Restrictions (<accessrestrict>) Use Restrictions (<userestrict>) Physical Location (<physloc>) Process Information (<processinfo>) Repository (<repository>) Maintenance Agency (<maintenanceagency>) Maintenance History (<maintenancehistory>)

PREMIS (version 3.0)	- XML schema that focuses on the preservation repository and its management; Can join other standards such as MODS, DC, EAD, METS etc. to cover metadata outside its scope and additional functions; and Applicable to support the preservation of digital objects, such as in the description of rendering environments for web content.	▪ objectIdentifier/Category preservationLevel significantProperties objectCharacteristics originalName storage signatureInformation environmentFunction/Design ation/Registry/Extension relationship linkingEventIdentifier/RightsS tatementIdentifier	▪ eventIdentifier/Type/DateTim e eventDetailInformation/Outc omeInformation linkingAgentIdentifier/ObjectI dentifier agentIdentifier/Name/Type/V ersion/Note/Extension linkingEventIdentifier/RightsS tatementIdentifier/Environme ntIdentifier rightsStatement/Extension
