Provenance

The provenance of works of fine art, antiques and antiquities is of great importance, especially to their owner. There are a number of reasons why painting provenance is important, which mostly also apply to other types of fine art. A good provenance increases the value of a painting, and establishing provenance may help confirm the date, artist and, especially for portraits, the subject of a painting. It may confirm whether a painting is genuinely of the period it seems to date from. The provenance of paintings can help resolve ownership disputes. For example, provenance between 1933 and 1945 can determine whether a painting was looted by the Nazis. Many galleries are putting a great deal of effort into researching the provenance of paintings in their collections for which there is no firm provenance during that period. Sometimes provenance can be as simple as a photograph of the item with its original owner. Simple yet definitive documentation such as that can increase its value by an order of magnitude, but only if the owner was of high renown. Many items that were sold at auction have gone far past their estimates because of a photograph showing that item with a famous person. Some examples include antiques owned by politicians, musicians, artists, actors, etc. In the context of discussions about the restitution of cultural objects in museum collections of colonial origin, the AfricaMuseum in Belgium started to publicly present information about such objects in its permanent exhibition in 2021. Researching the provenance of paintings , 1567: artist unknown. By the turn of the 17th century, this portrait was in the collection of John, 1st Baron Lumley, a fact indicated by the cartellino added to the painting at the upper right. It is now in the National Portrait Gallery, London The objective of provenance research is to produce a complete list of owners (together, where possible, with the supporting documentary proof) from when the painting was commissioned or in the artist's studio through to the present time. In practice, there are likely to be gaps in the list and documents that are missing or lost. The documented provenance should also list when the painting has been part of an exhibition and a bibliography of when it has been discussed, or illustrated in print. Where the research is proceeding backwards, to discover the previous provenance of a painting whose current ownership and location are known, it is important to record the physical details of the painting – style, subject, signature, materials, dimensions, frame, etc. The titles of paintings and the attribution to a particular artist may change over time. The size of the work and its description can be used to identify earlier references to the painting. The back of a painting can contain significant provenance information. There may be exhibition marks, dealer stamps, gallery labels and other indications of previous ownership. There may be shipping labels. In the BBC TV programme Fake or Fortune? the provenance of the painting Bords de la Seine à Argenteuil was investigated using a gallery sticker and shipping label on the back. Early provenance can sometimes be indicated by a cartellino, a ''trompe-l'œil'' representation of an inscribed label, added to the front of a painting. However, these can be forged, or can fade or be painted over. Auction records are an important resource to assist in researching the provenance of paintings. • The Witt Library houses a collection of cuttings from auction catalogs which enables the researcher to identify occasions when a picture has been sold. • The Heinz Library at the National Portrait Gallery, London maintains a similar collection, but restricted to portraits. • The National Art Library at the Victoria and Albert Museum has a collection of UK sales catalogues. • The University of York is establishing a web site with on-line resources for investigating art history in the period 1660–1735. This includes diaries, sales catalogues, bills, correspondence and inventories. • The Getty Research Institute in Los Angeles has a Project for the Study of Collecting and Provenance (PSCP) which includes an on-line database, still being compiled, of auction and other records relating to painting provenance. • The Frick Art Reference Library in New York has an extensive collection of auction and exhibition catalogues. • The Netherlands Institute for Art History (RKD) has a number of databases related to artists from the Netherlands. If a painting has been in private hands for an extended period and on display in a stately home, it may be recorded in an inventory – for example, the Lumley inventory. The painting may also have been noticed by a visitor who subsequently wrote about it. It may have been mentioned in a will or a diary. Where the painting has been bought from a dealer, or changed hands in a private transaction, there may be a bill of sale or sales receipt that provides evidence of provenance. Where the artist is known, there may be a listing all the artist's known works and their location at the time of writing. A database of is available at the International Foundation for Art Research. Historic photos of the painting may be discussed and illustrated in a more general work on the artist, period or genre. Similarly, a photograph of a painting may show inscriptions (or a signature) that subsequently became lost as a result of overzealous restoration. Conversely, a photograph may show that an inscription was not visible at an earlier date. One of the disputed aspects of the "Rice" portrait of Jane Austen concerns apparent inscriptions identifying artist and sitter. ==Archives==

, a rescue service for archival material: the number indicates its earlier provenance Provenance – also known as custodial history – is a core concept within archival science and archival processing. The term refers to the individuals, groups, or organizations that originally created or received the items in an accumulation of records, and to the items' subsequent chain of custody. The principle of provenance, also termed the principle of "archival integrity", and a major strand in the broader principle of respect des fonds, stipulates that records originating from a common source, or fonds, should be kept together – where practicable, physically, but in all cases intellectually, in the way in which they are catalogued and arranged in finding aids. Conversely, records of different provenance should be preserved and documented separately. In archival practice, proof of provenance is provided by the operation of control systems that document the history of records kept in archives, including details of amendments made to them. The authority of an archival document or set of documents of which the provenance is uncertain, because of gaps in the recorded chain of custody, will be considered to be severely compromised. The principles of archival provenance were developed in the 19th century by both French and Prussian archivists, and gained widespread acceptance on the basis of their formulation in the Manual for the Arrangement and Description of Archives by Dutch state archivists Samuel Muller, J. A. Feith, and R. Fruin, published in the Netherlands in 1898, often referred to as the "Dutch Manual". Seamus Ross has argued a case for adapting established principles and theories of archival provenance to the field of modern digital preservation and curation. Provenance is also the title of the journal published by the Society of Georgia Archivists. ==Books==

In the case of books, the study of provenance refers to the study of the ownership of individual copies of books. It is usually extended to include the study of the circumstances in which individual copies of books have changed ownership, and of evidence left in books that shows how readers interacted with them. Provenance studies may shed light on the books themselves, providing evidence of the role particular titles have played in social, intellectual and literary history. Such studies may also add to our knowledge of particular owners of books. For instance, looking at the books owned by a writer may help to show which works influenced him or her. Many provenance studies are historically focused, and concentrated on books owned by writers, politicians and public figures. The recent ownership of books is studied, however, as is evidence of how ordinary or anonymous readers have interacted with books. Provenance can be studied both by examining the books themselves, for instance looking at inscriptions, marginalia, bookplates, book rhymes, and bindings, and by reference to external sources of information such as auction catalogues. ==Pianos==

Provenance for pianos is authenticated before a piano is inducted into a museum, sold at an auction, or appraised for an estate or legal action, when it has extraordinary value in connection to a composer, performer, event or location that has become famous. For example, the piano that Wolfgang Amadeus Mozart used during the final 10 years of his life, is on display in the Mozarteum Museum in Salzberg, one of many historical pianos in museums around the world. The 300,000th Steinway piano that was presented to President Franklin D. Roosevelt by Theodore Steinway, on behalf of the Steinway family is on display in the White House. It is one of many pianos with a provenance that have extraordinary value because of art, sculpture or design incorporated into the cabinet. It has legs carved into golden eagles and figures painted on the body of the piano. For a piano, provenance can be established by starting with the authentication of the brand of manufacture and serial number, which will usually identify age. Then bills of sale, tuning records, bills of lading, concert programs that identify a piano by serial number, letters, famous signatures inside or on the outside of a piano, statements under oath in a court of law and photographs can all help authenticate a piano's provenance. Piano Provenance and Valuation Pianos can sell for millions of dollars, when the provenance is significant enough to increase its value well beyond what it would be worth as a musical instrument alone. When decisions need to be made in a court of law for a bankruptcy, or before a piano goes up for auction, or when an educational institution needs to establish a value for a deed of trust being established with the gift of a piano, then experts are usually hired to authenticate the piano's provenance. Piano provenance has emerged as a field of study with experts having college degrees in some specialty connected to the piano or to art combined with professional training and experience in the field. Most experts belong to some form of association. For example, Karen Earle Lile niece of Tony Terran and Kendall Ross Bean, members of the Preservations Artisans Guild, were chosen by Mercersburg Academy to research and authenticate the provenance of the Lennon-Ono-Green-Warhol piano before it was put up for sale to fund a Deed of Trust by the Shaool Family to Mercersburg Academy for future student scholarships. Because this piano was part of a famous lawsuit in 2000 and had extensive coverage as the "Lost Lennon Piano", when provenance research done by Lile was revealed by the Alex Cooper Auctioneers to the public, the provenance became the subject of dozens of newspapers and magazines that picked up the story. In the case of sculpture or art that are incorporated into the piano's cabinet, experts might be come from the field of art valuation and belong to an appraiser society such as the American Society of Appraisers or the International Society of Appraisers. ==Wines==

In transactions of old wine with the potential of improving with age, the issue of provenance has a large bearing on the assessment of the contents of a bottle, both in terms of quality and the risk of wine fraud. A documented history of wine cellar conditions is valuable in estimating the quality of an older vintage due to the fragile nature of wine. Recent technology developments have aided collectors in assessing the temperature and humidity history of the wine which are two key components in establishing perfect provenance. For example, there are devices available that rest inside the wood case and can be read through the wood by waving a smartphone equipped with a simple app. These devices track the conditions the case has been exposed to for the duration of the battery life, which can be as long as 15 years, and sends a graph and high/low readings to the smartphone user. This takes the trust issue out of the hands of the owner and gives it to a third party for verification. ==Science==

Archaeology, anthropology, and paleontology Archaeology and anthropology researchers use the word provenience (or alternatively find-spot) to refer to the exact location of discovery of an artifact, a bone or other remains, a soil sample, or a feature within an ancient site, Any given antiquity may have both a provenience, where it was found, and a provenance, where it has been since it was found. A summary of the distinction is that "provenience is a fixed point, while provenance can be considered an itinerary that an object follows as it moves from hand to hand." Another metaphor is that provenience is an artifact's "birthplace", while provenance is its "résumé". This can be imprecise. Many artifacts originated as trade goods created in one region, but were used and finally deposited in another. Aside from scientific precision, a need for the distinction in these fields has been described thus: while scholarly paleontology works make frequent use of provenience in the same precise sense as used in archaeology and paleoanthropology. While exacting details of a find's provenience are primarily of use to scientific researchers, most natural history and archaeology museums also make strenuous efforts to record how the items in their collections were acquired. These records are often of use in helping to establish a chain of provenance. Data provenance Scientific research is generally held to be of good provenance when it is documented in detail sufficient to allow reproducibility. Scientific workflow systems assist scientists and programmers with tracking their data through all transformations, analyses, and interpretations. Data sets are reliable when the processes used to create them are reproducible and analyzable for defects. Security researchers are interested in data provenance because it can analyze suspicious data and make large opaque systems transparent. Current initiatives to effectively manage, share, and reuse ecological data are indicative of the increasing importance of data provenance. Examples of these initiatives are National Science Foundation Datanet projects, DataONE and Data Conservancy, as well as the U.S. Global Change Research Program. Some international academic consortia, such as the Research Data Alliance, have specific groups to tackle issues of provenance. In that case it is the Research Data Provenance Interest Group. Computer science Within computer science, informatics uses the term "provenance" to mean the lineage of data, as per data provenance, with research in the last decade extending the conceptual model of causality and relation to include processes that act on data and agents that are responsible for those processes. See, for example, the proceedings of the International Provenance Annotation Workshop (IPAW) and Theory and Practice of Provenance (TaPP). Semantic web standards bodies, including the World Wide Web Consortium in 2014, have ratified a standard data model for provenance representation known as PROV which draws from many of the better-known provenance representation systems that preceded it, such as the Proof Markup Language and the Open Provenance Model. Interoperability is a design goal of most recent computer science provenance theories and models, for example the Open Provenance Model (OPM) 2008 generation workshop aimed at "establishing inter-operability of systems" through information exchange agreements. Data models and serialisation formats for delivering provenance information typically reuse existing metadata models where possible to enable this. Both the OPM Vocabulary and the PROV Ontology make extensive use of metadata models such as Dublin Core and Semantic Web technologies such as the Web Ontology Language (OWL). Current practice is to rely on the W3C PROV data model, OPM's successor. There are several maintained and open-source provenance capture implementation at the operating system level such as CamFlow, Progger for Linux and MS Windows, and SPADE for Linux, MS Windows, and MacOS. Operating system level provenance have gained interest in the security community notably to develop novel intrusion detection techniques. Other implementations exist for specific programming and scripting languages, such as RDataTracker for R, and NoWorkflow for Python. Whole-system provenance implementation for Linux • PASS – closed source – not maintained – kernel v2.6.X • Hi-Fi – open source – not maintained – kernel v3.2.x • Flogger – closed source – not maintained – kernel v2.6.x • S2Logger – closed source – not maintained – kernel v2.6.x • LPM – open source – not maintained – kernel v2.6.x • Progger – open source – not maintained – kernel v2.6.x and kernel v.4.14.x • CamFlow – open source – maintained – kernel v6.0.X Petrology (quartz, feldspar, lithic fragments) used to determine tectonic provenance in sandstones In the geologic use of the term, provenance instead refers to the origin or source area of particles within a rock, most commonly in sedimentary rocks. It does not refer to the circumstances of the collection of the rock. The provenance of sandstone, in particular, can be evaluated by determining the proportion of quartz, feldspar, and lithic fragments (see diagram). Seed provenance Seed provenance refers to the geographic location of a parent plant, from which seeds were collected. In the context of ecological restoration, seed provenancing refers to a seed-sourcing strategy that focuses on the geographic location of seed sources, as each provenance can describe the genetic material from that location. Local provenancing is a position maintained by ecologists that suggests that only seeds of local provenance should be planted in a particular area. However, this view depends on the adaptationist program – a view that populations are universally locally adapted. It is maintained that local seed is best adapted to local conditions, and that outbreeding depression will be avoided. Evolutionary biologists suggest that strict adherence to provenance collecting is not a wise decision because: • Local adaptation is not as common as assumed. • Background population maladaptation can be driven by natural processes. • Natural selection is changing rapidly due to climate change. and habitat fragmentation • Population fragments are unlikely to divergence by natural selection since fragmentation (< 500 years). This leads to a low risk of outbreeding depression. Provenance trials, where material of different provenances are planted in a single place or at different locations spanning a range of environmental conditions, is a way to reveal genetic variation among provenances. It also contributes to an understanding of how different provenances respond to various climatic and environmental conditions and can as such contribute with knowledge on how to strategically select provenances for climate change adaptation. ==Computers and law==

The term provenance is used when ascertaining the source of goods such as computer hardware to assess if they are genuine or counterfeit. Chain of custody is an equivalent term used in law, especially for evidence in criminal or commercial cases. Software provenance encompasses the origin of software and its licensing terms. For example, when incorporating a free, open source or proprietary software component in an application, one may wish to understand its provenance to ensure that licensing requirements are fulfilled and that other software characteristics can be understood. Data provenance covers the provenance of computerized data. There are two main aspects of data provenance: ownership of the data and data usage. Ownership will tell the user who is responsible for the source of the data, ideally including information on the originator of the data. Data usage gives details regarding how the data has been used and modified and often includes information on how to cite the data source or sources. Secure Provenance refers to providing integrity and confidentiality guarantees to provenance information. In other words, secure provenance means to ensure that history cannot be rewritten, and users can specify who else can look into their actions on the object. A simple method of ensuring data provenance in computing is to mark a file as read only. This allows the user to view the contents of the file, but not edit or otherwise modify it. Read only can also in some cases prevent the user from accidentally or intentionally deleting the file. ==See also==
