En jämförande studie av metadatascheman vid två statliga myndigheter

The purpose of this case study has been to investigate the development and implementation of Metadataschemas in two swedish governmental agencies. The interest of Metadata in relation to records managment has been significant lately due to the challenges posed by the digital environment. This has been manifesteted in international standards such as TS/ISO 23081 Metadata for records and the MoReq 2 Metadata specification issued by the DLM-forum. The extent to which these standard has influenced practice seems less overt however which has been one main motivation for this study.   The research questions adressed are: What has been the main purposes for the development of the Metadataschemas? Which standards and role-models have influenced the Metadataschemas? How has the implementation of the schemas been carried out? The case study has been conducted using a qualitative research method.

Skapa värde med integrationer - En studie av hur affärsvärde och konkurrensfördelar skapas från integrationer i industribranschen.

Companies will increasingly begin to link their applications, and the technology that makesthis possible is called integration. The more applications that are connected, the more of the company's data flows through these integrations. It is also clear that data analyses to create business value and to get competitive advantages against its competitors are important. In this paper, we examine how companies create business value and competitive advantages throughthe integration platforms and Metadata from the integrations. We have interviewedpeople from three companies in the industrial sector, each with an integration platform.We have also interviewed Enfo Zystems, a company that provides development andmanagement of integration platforms to these customers.

Vi lämnar spår på Internet : Integritet i relation till loggning på UpUnet

This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..

Metadata för det digitala biblioteket : Objektbeskrivning av elektroniska resurser

Cataloguing electronic documents makes new demands on libraries. This thesis discusses the Metadata formats Dublin Core and MARC which are, individually or in combination, commonly used for object description in the digital library.The formats are studied with particular emphasis on characteristics such as underlying reasoning (ambitions during the development of the formats), flexibility (possibilities of expansion and adaption to new demands) and interoperability (cooperation between different Metadata formats). The formats are dealt with in their context, i.e. we discuss what types of documents the formats are meant to describe, what environment they were originally created for, what functions they are meant to fill (to find, identify, select and acquire/obtain entities), and also how these factors are related. The Swedish projects SAFARI (which uses Dublin Core) and NetSök (which uses MARC) are presented briefly.

Metodutveckling för framställande av dynamisk systemkarta

I komponentbaserade system är det viktigt att ha kontroll över vilka komponenter som har beroenden till varandra för att undvika att delar av systemet slutar fungera vid exempelvis en komponentuppdatering. I detta arbete undersöks hur komponenter kan identifieras, samt hur olika typer av beroenden kan spåras. Arbetet är utfört som ett uppdrag givet av Sandvik Systems Development (SSD), vilket är ett av Sandvik-koncernens två internationella IT-bolag. Målet med uppgiften är att utforma en modell som tar fram information för komponenterna, samt kartlägger dess beroenden på Windows-plattformen. Mycket information om ett system finns att hämta i olika typer av ?statiska? Metadata-filer som automatiskt genereras vid skapandet av en lösning i Visual Studio.

Energieffektiv design av ett inbyggt flashminneshanteringssystem

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system Metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.

Funktionella krav på metadata: En undersökning av Dublin Cores överensstämmelse med FRBR

The purpose of this master thesis is to examine how Dublin Core corresponds to the findings in the IFLA report Functional requirements for bibliographic records FRBR, and what consequences this correspondence has on the usability of Dublin Core as a bibliographic standard. While the study describes the conceptual model of FRBR and the entities work, expression, manifestation and item, its main focus is the mapping of attributes and relationships to the user tasks defined, namely to find, identify, select and obtain entities. The study makes a comparison between data that FRBR rates as highly important for any user task, and the elements defined in DCMI Metadata Terms. The outcome of the comparison is then analyzed as to how it affects Dublin Core's possibilities to assist in the different user tasks, and common problems are discussed. The results show that problems in expressing attributes and relationships through Dublin Core elements concern all of the four user tasks.

Weblogindex: En studie av weblogindex utifrån Lancasters processmodell över traditionell indexering.

Many new electronic publication systems have arisen in the past few years, one of them is the weblog. In 1999 there were 23 weblogs, today there are millions thus a need for organisation has appeared, both special Metadata and subject indexes have been invented and created. Due to the large amount of the latter we have in this thesis decided to concentrate on those close by the Scandinavian weblogindexes. A more international perspective would however have been possible, as very little is written on the topic. We have looked at these selected weblogindexes, trying to determinate whether they agree with F.

Kategorisering av bilder i kameramobiler - Hur kan man kategorisera och söka bilder i kameramobiler på nya och innovativa sätt?

Då allt fler mobiltelefoner utrustas med en megapixelkamera har vi valt att undersöka hur människor hur människor hanterar bilder tagna med kameramobilen. Vi har inriktat oss att ta reda på hur människor kan kategorisera och söka efter bilder i en mobilkontext på nya och innovativa sätt. Vi har samlat in data från en förstudie bestående av ostrukturerade observationer och intervjuer. Därefter genomförde vi en webbekätundersökning med 249 respondenter och avslutade med intervjuer av två exporter inom området. Vår studie visar att människor har relativt få bilder i sina kameramobiler samt att de inte har några större svårigheter att hitta dem.

Införande av ett dokumenthanteringssystem på SMHI

Den ostrukturerade dokumenthantering, som idag förekommer på avdelningen Ida på företaget SMHI, gav upphov till detta examensarbete. Ett dokumenthanteringssystem har införskaffats till avdelningen. Dokumenthanteringssystemet är en produkt från Microsoft med namnet SharePoint Portal Server (SPS), vilken levererats av WM-data. SPS är relativt ny på marknaden, vilket gör att erfarenheter saknas kring produkten. Syftet med dokumenthanteringssystemet är att samla alla dokument på samma plats, vilket gör dem lätt tillgängliga för alla berörda.

Spela för nöje eller spela för kunskap? : Lärares uppfattningar av IT-baserade matematikspel och dess konsekvenser på elevers kunskapsutveckling

Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of Metadata is needed. This resulted in an investigation about Metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.

ETL-processen : teori kontra praktik

AbstractNowadays, companies and organizations manage large amounts of data to be used as support in decision making. A good solution for data management is in the form of data warehouses. A data warehouse is used to gather information from multiple sources within a company and arrange the information in a way that makes it easy to retrieve and analyze. Designing a data warehouse is not a simple task. The study herein will focus on what a data warehouse is and how the ETL process is used for data storage in the data warehouse. ETL stands for Extract, Transform and Load and is the process that retrieves data, transforms it and finally loads it into the data warehouse.

Bilden av bilden bildbeskrivning i ABM-samarbetet PictureAustralia, en fallstudie.

This thesis aims at exploring a national collaborative gateway-service, PictureAustralia, hosted at the National Library of Australia. This will be done by means of investigating some underlying principles for descriptive standards and conventions as of the library discourse which is the objective of bibliographic control and access. The reason to do this is to bring some main features of these principles into the context of a cross-institutional cooperation between libraries, galleries/museums and archives in a picture database service. The attention will lay on the objectives of what functions the system is designed to perform to give access, as defined by Elaine Svenonius in the Intellectual Foundations of Information Organization 2000, and how these objectives will affect this particular database-service collocating performance, which is a system- and logical approach. Though, this study will be done in an explorative and qualitative way, by a case-study, which is to examine some sample Metadata records emanated from different institutions in this project.

Dynamiska resurser på Geodataportalen : teori och praktik

Geodata finns idag tillgängligt via geodataportaler runt om i världen. På dessa geodataportaler beskrivs datamängder och tjänster som kommer från olika myndigheter. Geodatasamverkan har uttryckt intresse för att kunna beskriva realtidsresurser på dessa portaler med hjälp av Metadata. Utifrån ett samarbete mellan SMHI och Lantmäteriet har denna studie tagits fram där en dynamisk realtidsresurs från SMHI testas beskrivas med Geodataportalens nuvarande struktur. Befintlig litteratur har undersökts för att presentera en bakgrund.

Ontologibaserat dokumenthanteringssystem implementerad som datakatalog i legacymiljö

Ett ökande behov av Metadata har identifierats och i många verksamheter finns ett behov att skapa och lagra Metadata som beskriver någon typ av data. Detta har drivit på studier av datakataloger som betraktas som lösningen på Metadatabehovet. Detta arbete har behandlat att specificera ett dokumenthanteringssystem byggd på en datakatalog för en verksamhet i en utförd fallstudie. Den behandlade dokumentdatakatalogen inkluderar en ontologi för att skapa ändamålsenlig sökning i en legacymiljö.I den framtagna specifikationen på arkitekturavgränsningar för en dokumentdatakatalog är det kännetecken såsom integrerad, skalbar, robust, anpassbar och öppen som införlivar en sund arkitektur. I specifikationen ingår även ett antal krav som utöver kännetecknen bör följas för en god arkitektur.
